Upgrading a sightseeing bus ticket is arithmetic. In Singapore the two-day ticket and the same two days with a night tour sit US$28 apart, while that night tour sells on its own for US$37.50, so the upgrade is the cheaper way to buy it if you will still be in town that evening. Sydney charges AU$24 for a second day on the very same two routes and another AU$34 above that for a harbour cruise and a night drive. London's ladder runs the other way, with the second day costing less than the single add-on it replaces. The shape repeats in every city below: you are paying for routes you cannot otherwise reach, hours you may not use, and extras that have their own price tags.
Every figure here is the operator's online adult rate for a standard date, which is not what you pay at the kerbside. London's day pass costs £43.99 at the counter and Vienna's top ticket €59.00, against the online rates in the tables below. Dynamic pricing moves those totals by date and season, but the rungs of a ladder shift together, so the deltas between tiers are the part you can plan around.
What an upgrade buys, and what it leaves unchanged
Route gates decide more than ticket length
Big Bus New York's 24-hour entry ticket covers the Downtown Loop only, and the 48-hour tier opens the Uptown Loop. Hong Kong cuts harder: the cheapest tier buys one route of your choice plus a one-way Star Ferry crossing, and the next rung up covers the Island, Stanley and Kowloon routes with a return ferry. In both cities the entry ticket is a route restriction, and extra hours cannot repair it.
Vienna and Sydney work the other way. Every Vienna tier rides the same Red city loop and Blue Schönbrunn loop, and every Sydney tier below the top one covers both the City and Bondi routes. There, the upgrade buys hours and add-ons, so the only question left is whether you will use them.
Rolling hours against one calendar day
London sells both clocks side by side, and mixing them up costs you half a day. The One Day ticket at £32.00 runs until the buses stop that evening, so buying it at 14:00 spends most of the money on an afternoon. The 24-hour ticket starts a countdown when you activate it in the app, which suits a Friday arrival who also wants Saturday morning. Activation is final: the clock cannot be paused, extended, or moved to a second device.
The eight passes, ladder by ladder
Rows run from the cheapest usable tier upward, so you can see which rung opens routes and which one only adds hours. Prices are the operators' online rates in the currency they charge, because that is the figure your card will be converted from.
| Pass | City | Entry tier | Middle tier | Top tier | Where it falls down |
|---|---|---|---|---|---|
| Big Bus London | London | Discover £36.99 (24 hours, one-way Thames cruise) | Essential £46.99 (48 hours, three guided walking tours) | Explore £56.99 (48 hours plus a 75-minute evening tour) | Central traffic delays are routine, and the open-top departures have no shelter upstairs |
| Big Bus New York | New York | Discover US$62.00 (24 hours, Downtown Loop only) | Essential US$83.00 (48 hours, both loops, two-hour night tour) | Explore US$99.00 (72 hours plus a Circle Line cruise); a US$135.00 package adds the Empire State Building and the Statue of Liberty ferry | The entry tier is a route gate, not a short pass |
| Big Bus Vienna | Vienna | Discover €37.00 (24 hours, both loops) | Essential €42.30 (48 hours, plus hot dog and Swarovski gift) | Explore €51.30 (72 hours, plus a guided walking tour) | The evening tour is not included at any tier |
| Big Bus Singapore | Singapore | Discover US$53.00 (one day on the Yellow and Red lines) | Essential US$55.00 (two days plus the Cityscape Panoramic Tour) | Explore US$83.00 (two days plus a three-hour night tour) | Both daytime lines are short loops, so the top tier is effectively a night-tour purchase |
| Big Bus Sydney & Bondi | Sydney | Discover AU$75.00 (24 hours, City and Bondi routes) | Essential AU$99.00 (48 hours on the same two routes) | Explore AU$133.00 (48 hours plus a harbour cruise and a 90-minute night drive) | The night drive is one continuous circuit with a live guide, not a hop-on loop |
| Big Bus Hong Kong | Hong Kong | Discover US$55.00 (24 hours on one chosen route, one-way ferry) | Essential US$76.00 (24 hours on all three routes, return ferry) | Explore US$101.00 (48 hours plus a Peak Tram, water taxi or sampan inclusion) | Headways of 45 and 60 minutes on the two island routes punish a missed bus |
| City Sightseeing Amsterdam | Amsterdam | Bus & Boat, 24 hours, €35.00 (list price €72.00) | 48-hour version of the same combination | Combination with a museum, from €45.00 | Bus and boat share one validity window, and the boat is not wheelchair accessible |
| Stromma Copenhagen | Copenhagen | Bus only, 24 to 72 hours, DKK 279 | 24-hour bus and Classic Canal Tour, DKK 409 | 48 hours DKK 419, 72 hours DKK 439 | Most riding happens on the Red Line; the other two lines run a few departures a day |
The second rung is usually where the value sits, because it costs a fraction of the entry tier and often doubles your days. The top rung is where the ladders stop being comparable, since each operator fills it with something different.
What a tier costs per stop
Dividing the price by the stops a tier covers puts the ladders on one scale, even with six currencies in play. I keep every figure in the currency the operator charges, because a fixed conversion would hide the rate your card applies on the booking date.
| Pass and price | City | Published stops the tier covers | Cost per stop |
|---|---|---|---|
| Big Bus London Discover, £36.99 | London | 28 on the Red Route | £1.32 |
| City Sightseeing Amsterdam Bus & Boat, €35.00 | Amsterdam | 17 across bus and boat | €2.06 |
| Big Bus Vienna Discover, €37.00 | Vienna | 13 on the Red Route | €2.85 |
| Big Bus Hong Kong Essential, US$76.00 | Hong Kong | 22 across three routes | US$3.45 |
| Big Bus New York Discover, US$62.00 | New York | 13 on the Downtown Loop | US$4.77 |
| Stromma Copenhagen bus only, DKK 279 | Copenhagen | More than 20 across three lines | About DKK 14 |
These are published stop counts, not your stops. Two hop-offs on Vienna's 24-hour pass work out at €18.50 each, which is why the pass only makes sense when it doubles as transport for the day. A Wiener Linien 24-hour ticket for unlimited metro, tram and bus travel in the core zone costs €9.70 (per Wiener Linien). Over three days, Vienna's 72-hour Explore works out at €17.10 a day against €9.70 a day on city transport, and the €22.20 difference is what you pay for the open upper deck, nine-language commentary, a direct drop at Schönbrunn's gates and two gift-shop extras. Where the bus is a sightseeing loop and not your transport, a metro day ticket wins on price, and hop-on bus fares against metro and city buses compares that gap city by city.
Activation, screenshots, and the rules that bite
Buying online is cheaper than paying a seller at a major stop, and the digital ticket arrives with rules that decide whether your pass works at all. Under the Big Bus terms and conditions, a booking must be added to the app with its booking reference before activation, and screenshots, inactive app passes and confirmation emails are not accepted for travel. Tickets are non-transferable, the clock starts the moment you activate, and a flat phone battery can leave you buying a second ticket at full price. Working mobile data at the stop is part of the product.
Combination tickets can run two clocks at once. City Sightseeing Amsterdam applies one 24- or 48-hour window to bus and boat together, so you cannot ride the bus on Tuesday and save the boat for Thursday, and the buses finish for the day hours before the boats do.
Copenhagen needs one extra step. The Stromma bus ticket activates on the driver's first scan, while the canal boat is a separate product: you take the voucher to a ticket house at Nyhavn or Ved Stranden and swap it for a time-slotted canal pass. I walked to Ved Stranden expecting to board the next boat, spent twenty minutes at the counter, and watched my intended departure leave without me.
Two rules get ignored until they matter. Refunds are conditional: the terms promise a full or partial refund when the operator cannot run the service through circumstances within its control, and claims have to be made in writing, which is why so many passenger complaints end at a customer-service inbox. Conduct rules are enforced too, with no food or drink apart from bottled water, no alcohol, no smoking or vaping, and a requirement to stay seated upstairs while the bus is moving.
App tip: add the booking to the operator's app on hotel Wi-Fi the night before, and wait until you are standing at the stop to press activate. Carry a power bank, and download the app's interactive map before you leave the hotel, since each map pulls about 10MB of data.
Five checks before you pay
- Weather substitution: the terms allow a closed-top bus in bad weather, so a wet day can cost you the view rather than the fare.
- Voucher swaps: boat combinations usually need the voucher exchanged at a ticket house for a time slot, and the popular slots go by midday.
- Night tours: these are locked to the date and departure time chosen at booking and cannot be transferred, so buy one only once your evening is fixed.
- Seating: no pass reserves a seat, and services run first-come, first-served. On busy afternoons, board a stop or two before the one you want and stay on.
- Route status: check the operator's service page on the morning of travel for closed stops and diversions, which are routine in London and Vienna during events.
How long the loops take, and when the last bus leaves
A published 45-minute headway means a missed bus costs most of an hour, and a last full circuit in the mid-afternoon ends your riding day long before dinner. These are the operators' own figures.
| Route | City | Full loop | Frequency | First and last departure |
|---|---|---|---|---|
| Red Route | London | 2 h 30 min | Every 15 to 20 min | 08:30 / 17:45 from Stop 2, Hard Rock Cafe |
| Blue Route | London | 3 h 35 min | Every 20 min | 10:34 from Victoria / 20:08 at Victoria |
| Green Link | London | 1 h 10 min | Every 45 min | 08:30 / 15:15 from Woburn Northbound |
| Downtown Loop | New York | 1 h 30 min | Every 30 min | 09:00 / 16:30 at M&M's World, 7th Avenue |
| Red Route | Vienna | 1 h 40 min | Every 20 to 30 min | 09:30 / 16:30 from Opera, Walfischgasse |
| Hong Kong Island (Red) | Hong Kong | 1 h 15 min | Every 45 min | 10:00 / 17:00 from Central Star Ferry Pier 7 |
| Stanley (Green) | Hong Kong | 2 h | Every 30 min | 10:30 / 16:30 from Central Star Ferry Pier 7 |
| Kowloon (Blue) | Hong Kong | 1 h 20 min | Every 60 min | 10:00 / 17:00 from Avenue of Stars |
| Red Line | Copenhagen | 1 h 30 min | Every 45 min | 09:30 from Tivoli; last full tour 15:35 from Tivoli and 16:00 from Ved Stranden |
| Green Line | Copenhagen | 45 min | Twice daily | 12:00 and 14:00 from Tivoli |
| Purple Line | Copenhagen | 55 min | Three times daily | 10:45, 12:45 and 14:45 from Tivoli |
| Bus loop and boat circuit | Amsterdam | Bus just over 1 h; boat about 2 h | Bus about every 25 min; boat every 30 to 45 min | Bus 10:00 to 17:00, boat 09:30 to 17:45, from Central Station East |
The Big Bus London service information page is the one to open before you travel. It listed Stop 1 at Green Park out of service until further notice, Stop 14 at Covent Garden suspended because of a low-hanging tree with a temporary boarding point outside the Waldorf Hotel, and Stop 26 at Buckingham Palace closed on Mondays, Wednesdays, Fridays and Sundays from 10:00 to 12:30 for the Changing of the Guard. It also flags the London Eye closing for annual maintenance from 11 to 24 January 2027, which matters if you buy a combo that includes it.
Where the extra money is worth it
London and Vienna: cheap second days, early nights
In London the 48-hour Essential tier is the rung worth having, at £10 above the 24-hour pass for a second day, the Thames cruise and three guided walking tours. The Explore tier costs another £10 and adds only the evening tour, which is fair value at that margin because the standalone London Evening Tour sells for £29.99 and leaves at 19:30 and 21:00 from Stop 12 at the London Eye. On a three-day trip, buy the Essential and add the evening separately on the night you want it.
Vienna's ladder rewards a two-day visitor for a different reason: the 48-hour Essential is the cheapest route to a second day on the same two loops, and its hot dog and Swarovski add-ons are minor extras rather than the point of the ticket. Late in the year the seasonal product is the better buy, with the Christmas Lights Tour at €44.10 running from 6 November 2026 to 3 January 2027 and combining a one-hour panoramic drive with entry to the Imperial Lights gardens at Schönbrunn.
New York and Hong Kong: gates you cannot buy your way past
New York's night tour is the best-value add-on in this pair of cities. Standalone it costs US$67.00 with live guides and departures at 19:00 and 20:00; inside the 48-hour tier it comes as part of the package. The 13-stop Downtown Loop runs on a 30-minute headway, so the loops reward a plan: ride one circuit end to end to orient yourself, then use the bus to link two or three clusters instead of treating it as a taxi between every stop.
Hong Kong's extras are the reason to look past the entry ticket. The 24-hour all-routes tier adds the return ferry, the 48-hour tier adds your choice of the Peak Tram Special Combo, a water taxi cruise or a sampan tour, and two packages sit alongside them: the Essential ticket with a one-way Airport Express train ticket at US$83.00, and the entry ticket with the Peak Tram and Madame Tussauds at US$110.00. The 60-minute night tour is separate, at US$44.00. With headways of 45 and 60 minutes on the two island routes, treat the timetable as a schedule and not a suggestion.
Copenhagen, Amsterdam and Sydney: water and night circuits
Copenhagen's pass covers three lines, and only the Red Line is a true loop. The Green Line runs out to the Home of Carlsberg and back, and the Purple Line links Christianshavn with Refshaleøen, where the Reffen street food market opens in summer only. If your list is Nyhavn, Amalienborg and the Little Mermaid, the Red Line does the work and the canal boat fills the second half of the day.
Amsterdam's bus and boat routes share three stops, at Central Station East, the Passenger Terminal and World of Gassan, which are the places to switch without losing time. On a warm afternoon I rode the bus first and finished on the water, mainly because the boats run an hour later and the canal ring looks better at the end of the day. The ticket also includes a free visit to the Gassan Diamonds workshop, which I skipped.
Sydney's ladder exists for one reason: the 48-hour Explore tier adds the hop-on hop-off harbour cruise and the 90-minute night drive over the 48-hour Essential. Standalone, that night tour costs AU$69.00, and a family-oriented Big 5 bundle at AU$145.00 swaps the boat and the night ride for four attraction entries. Choose the extras you will use, because the day routes are identical at both 48-hour tiers.
Audio commentary: what you get, and where it drifts
Live guides and recorded commentary are different products, and the operator decides which one you get. In London the Red Route carries live guides while the Blue Route runs recorded commentary in 12 languages, with free wired earphones handed out at the door (see Big Bus London multi-language tours). Vienna and Hong Kong both use pre-recorded commentary in nine languages, City Sightseeing Amsterdam plays GPS-triggered commentary in 18 languages with earphones you keep for the next leg, and Stromma's Copenhagen buses run 14 languages plus free Wi-Fi. Stromma's canal boats switch to live guides in English and Danish or six-language audio.
Recorded commentary is where the complaints cluster. Reviews on Big Bus's London profile describe commentary that names the wrong building, and several reviewers call it flippant, with little history in it. The mismatch is worst when a bus is diverted, because the script cannot know where the bus has gone, and the operator reserves the right to run closed-top buses in bad weather, which removes the upper deck the commentary was written for. One detail decides your comfort: the headphone sockets on Big Bus live guides and tour commentary vehicles are 3.5mm and Bluetooth is not supported, so pack wired earphones if you dislike the free pair.
What passengers complain about
Big Bus Tours London carries a Trustpilot score of 1.9 out of 5 across more than 11,000 reviews, and the themes repeat: long waits at stops, buses arriving full so queued passengers are left behind, bus tracking in the app that does not match what is on the street, and refunds that take persistence. The full-bus problem is written into the operator's own terms, which state that seating cannot be guaranteed on either deck and that services run first-come, first-served. The same company's Vienna profile sits at 3.0 from around 545 reviews, so London is the weak city in that network, and Vienna is not.
City Sightseeing Amsterdam's own ticket page shows 4.5 across 74,000 bookings, and the split inside those reviews is useful: passengers praise the canal boat and the live map in the app, and criticise the bus loop, the missing stop signage and a wait one reviewer timed at over an hour at Central Station. Two reviews describe the bus route as circling outside the historic centre, which the stop list supports: nine bus stops, several of them beyond the canal ring.
Stromma's Copenhagen bus-and-boat combination collects 4.5 from roughly 3,800 Google reviews while its bus-only product collects 4.0 from about 74, and the boat is the part people remember. Tripadvisor's Big Bus London page, with more than 13,000 reviews, runs on the same complaints as Trustpilot, right down to the wait in the rain.
Accessibility is the one place where the brochures and the small print disagree. The Amsterdam buses take wheelchairs, but riders have to board and leave independently for safety reasons, and the boats are not accessible at all. Stromma cannot carry wheelchair users who cannot transfer into a regular seat on its Copenhagen buses, and wheelchairs go in the space the driver also uses for luggage and buggies. If any of that applies to your group, ask the operator directly before booking, because these limits are in the suppliers' own documentation.
Alternatives worth pricing first
Three operators share the London streets, and the first ticket you find is not always the right one. Golden Tours sells 24-, 48- and 72-hour loops with the Thames cruise and a walking tour included, and scores 3.7 from around 2,000 reviews on the same platform where Big Bus London scores 1.9. Tootbus, which took over The Original Tour's routes, sells its London Discovery pass over 24, 48 and 72 hours on an electric fleet. Bustronome belongs to a different category: a glass-roof dining bus with a set meal and no hop-on rights, worth its price only when the meal is the point of the evening.
Then there is the transport you have already paid for. Vienna's metro, tram and bus lines cover the Ringstrasse, Schönbrunn and the Prater on a €9.70 day ticket, and the tram and metro networks in Amsterdam and Copenhagen reach the same central stops the sightseeing loops serve. The buses earn their price when you want the upper deck, the commentary, and a fixed circuit that saves you from planning one. For multi-day trips, my two-day Amsterdam bus and canal loop shows how the bus-and-boat clock works in practice when you only have one afternoon and one morning.
Upgrades I would skip
Vienna's Panoramic Tour Ticket is the weakest product on this page. At €30.00 it buys 70 minutes in a seat with no hop-on rights, while the 24-hour Discover ticket in the table above costs €7 more and covers both loops all day. If you want the view without the pass, ride tram 1 or tram 2 around the Ring instead.
Vienna's 72-hour Explore tier is the one to drop on a two-day visit. The routes are identical at every tier, the third day only exists if your itinerary does, and the evening tour, the only Vienna add-on I would pay for, is not in the package. It is sold separately at €28.00.
New York's 72-hour Explore tier adds a third day and a one-way Circle Line cruise over the 48-hour pass. That cruise is not a hop-on hop-off service, so unless you have three full days in Manhattan, the 48-hour tier with the night tour is the complete product.
Hong Kong's entry ticket is the one to refuse if you want more than a single route: it caps you at one line for a full 24 hours, and you cannot upgrade mid-journey without buying a new ticket.
In Singapore the night tour is the only thing the top tier adds. If your evenings are already booked, the two-day tier is the whole purchase, and the extra money buys an activity you will not attend.
