Card Sharp: The Break-Even Maths on European City Passes in 2026

City cards are sold like a magic trick: one swipe, everything included, queue jumped, wallet closed. But a sightseeing pass is not a discount — it's a bet. You're betting that you'll visit enough paid attractions, use enough public transport and take enough included extras to clear the card's price. Lose that bet and you've simply prepaid for a weekend you weren't going to have.

That's not a reason to avoid them. It is a reason to do five minutes of sums before you tap your card at the airport. Here's how the maths works in three popular European cities for 2026, using approximate prices converted to pounds at the time of writing. Check current rates before you buy — city cards change their line-up more often than you'd think.

The only sum that matters

Ignore the glossy leaflet. A city card only saves you money when:

Card price − value of transport you'd definitely use − value of extras you'd definitely pay for = less than the pay-as-you-go entry fees for the sights you'd definitely visit.

The trouble is the middle bit. Cards love to bundle in canal cruises, minor museums, shop discounts and a free biscuit, then count all of it at full face value. If you wouldn't have bought it separately, it isn't saving you anything. It's just making the card look busier.

Amsterdam: three museums or bust

A 48-hour I amsterdam City Card is roughly £78. It includes GVB public transport, a canal cruise and entry to a long list of museums. The big hitters — the Rijksmuseum at about £22 and the Van Gogh Museum at about £20 — are in. The Anne Frank House is not, and you'll need to book that separately anyway.

Take away two days of transport, worth about £24, and you need £54 of attractions to break even. That's roughly three paid sights at £18 each. A realistic two-day itinerary of Rijksmuseum, Van Gogh and one smaller museum gets you there. Add the canal cruise and you're ahead by a few pounds. Skip one museum and the card flips from a small win to a £12–£20 loss.

Three days changes the picture. A 72-hour card is around £95; transport is worth about £36, so you need £59 of entry. That's four solid attractions — doable if you're a museum person, less so if you're planning to spend Saturday afternoon in a brown café.

Copenhagen: transport is the swing factor

A 48-hour Copenhagen Card costs about £85 and covers public transport in zones 1–4 plus a long list of attractions. The card's reputation rests on Tivoli, Rosenborg, the canals and a handful of museums.

Transport for two days is worth roughly £20. That leaves £65 of attractions to find. Tivoli (about £20), Rosenborg (about £15), a canal tour (about £15) and the National Museum (about £12) total £62 — just short. Add Christiansborg at about £18 and you're £15 ahead. In other words: four attractions is marginal, five is a clear win, three is a donation to the tourist board.

Season matters here. Tivoli is not a year-round certainty, and if it's closed during your trip the card's break-even point moves sharply against you. The same goes for any trip where you plan to walk everywhere: if you barely touch the Metro, you've paid for transport you didn't use.

Lisbon: the cheap card with a catch

A 48-hour Lisboa Card is around £38, which makes it feel like a no-brainer. It includes transport on the Metro, trams and funiculars, plus entry to a cluster of museums.

Take transport at about £12 for two days, and you need £26 of attractions. Jerónimos Monastery (about £12), Belém Tower (about £8) and the National Tile Museum (about £8) total £28 — a £2 win. That's genuinely thin. The card also advertises discounts at Sintra palaces rather than free entry, and the famous Tram 28 is often too full to board, so the 'free tram' is not always the gift it appears.

For three days, a 72-hour card at about £48 needs roughly £30 of attractions after transport. Three paid sights clears it, but only just. Lisbon is the city where the card is easiest to love and hardest to justify: the sums work, but the margin is so small that one change of plan wipes it out.

The add-ons that flatter the card

City cards are marketed on a long list of inclusions, and that list is doing a lot of emotional work. Watch for:

• Canal cruises you wouldn't have taken. They're priced at £15–£20 on the leaflet, but if you'd rather walk, that's not a saving.
• Minor museums. Ten small attractions at £6 each look impressive. You're not visiting ten.
• Shop and restaurant discounts. A 10% discount at a gift shop is not a reason to buy a card.
• Transport you'd walk anyway. Compact centres like Amsterdam and Lisbon are walkable. Count only the journeys you'd actually make.
• 'Skip the line' claims. Often it means a separate entrance, not a faster security queue. At somewhere like Jerónimos, everyone queues.

Trip shapes where the pass wins

The wet-weather museum crawl. If you're going in November and plan to be indoors from 10am to 5pm, a card that covers four or five museums will usually pay. Copenhagen in particular rewards this.

The first-timer's three-day dash. Three days, five or six paid sights and regular tram or Metro use is the sweet spot. Amsterdam's 72-hour card and Copenhagen's 72-hour card both start to look sensible here.

The transport-heavy city break. If your hotel is outside the centre and you'll be hopping on and off public transport all weekend, the bundled travel card can carry the maths on its own. Lisbon and Copenhagen are the clearest examples.

The verdict

A £50 city card is not a scam. It's a bulk-buy deal with a narrow sweet spot. Buy it when your itinerary is already full of paid attractions, when you'll use public transport more than twice a day, and when the extras on the list are things you'd have booked anyway. Skip it when your plan is one big museum, a lot of walking and a long lunch — because in that trip, the card isn't saving you money. It's just moving it from your pocket to a plastic rectangle.
