How to plan a 24-hour trip

Aim to be in the center, bags dropped, between 9 and 10 a.m. Most plans on the site start then. Kraków's starts at 8:30 a.m. so you are on Wawel Hill when the castle opens at 9; Edinburgh's at 9 a.m. for a 9:30 castle slot. Arrive at lunchtime and you lose the morning sight, not the evening.

Pick the day before the flight. Friday and Saturday work in most cities, because the weekly closures fall early in the week:

• Monday: the Uffizi in Florence, Wawel Castle routes in Kraków, Jerónimos Monastery in Lisbon, the Accademia in Venice, Shinjuku Gyoen in Tokyo.
• Tuesday: the Louvre, the Reina Sofía in Madrid, Topkapı Palace in Istanbul, Gyeongbokgung in Seoul, the Art Institute of Chicago, Boston's MFA.
• Wednesday: the Met in New York.
• Sunday: Florence's cathedral, Westminster Abbey and St Paul's for sightseers, and York Minster except 12:45 to 2:30 p.m.

If you can travel by train, do. London to Bath is 73 minutes from Paddington, to York 105 minutes from King's Cross and to Paris 136 minutes on Eurostar, each arriving in the center. From New York, the Acela reaches Philadelphia in 69 minutes and Washington, DC in 175. Our train-from-London ranking sorts the options.

Travel with carry-on only. Checked bags add a wait at both ends of a trip with no slack. In the US, the TSA limits liquids, gels and creams to travel-size containers of 3.4 ounces (100 ml) each, in one quart-sized bag. Most UK airports still apply a 100 ml limit, with liquids in one clear, resealable bag of up to a liter, about 20 cm (8 inches) square. GOV.UK notes that some airports now allow containers up to 2 liters, so check yours before you pack.

On arrival, the hotel is the first place to leave a bag, even hours before check-in. If you arrive by train in London, Visit London lists staffed left-luggage desks, run by Excess Baggage Company, at King's Cross, St Pancras, Paddington, Euston, Liverpool Street, Waterloo, London Bridge and Victoria, and in the arrivals halls at Heathrow, Gatwick and Stansted. In Iceland, the 7:30 a.m. Reykjavik Excursions bus from Keflavík runs to the Blue Lagoon, where you can store a bag for $4.10 (£3.10; ISK 500) before continuing into town.

Stay in the center. One night does not justify a cheaper room 40 minutes out: you would pay the fare twice and lose the late walk back. Every hotel price on our city pages is the cheapest double in a hotel of 3 stars or more with a guest rating of 8/10 or better, inside a named central area, on two Fridays: January 15 and June 11, 2027.

Those two dates show how much the night can swing. Manchester was $76 (£57) in January and $356 (£267) in June. Copenhagen went from $104 (£78) to $269 (£202). Nashville's June Friday fell on CMA Fest, at $428 (£321) against $191 (£143) in January. Singapore barely moved: $61 (£46) and $62 (£46). Before you book, check the city's festival calendar, and in Venice check the access-fee days: the fee applies on 72 days between March 26 and August 15, 2027, from 8:30 a.m. to 4:30 p.m., including June 11 to 13.

Take the fastest public option and learn its fare before you land. Copenhagen's M2 metro reaches Kongens Nytorv in 14 minutes for $4.50 (£3.40; DKK 30). London's Elizabeth line takes 32 minutes from Heathrow for $21 (£15.50). Where a taxi has a fixed fare, know it: $63 (£47; €56) from Charles de Gaulle to the Right Bank, $62 (£46; €55) from Fiumicino to anywhere inside Rome's Aurelian Walls, $37 (£28; €33) from Madrid's airport to anywhere inside the M-30. In Reykjavík the gap is widest: the Flybus costs $33 (£25; ISK 3,999), the fixed taxi $185 (£139; ISK 22,500).

Buy a day ticket only where it beats two or three single fares, and check whether it covers the airport:

In Florence, York and Bath you need none: the plan is walked. Florence's single bus and tram ticket is $2.20 (£1.70; €2), and bus fares in England outside London are capped at $4 (£3) until March 2027.

One sold-out slot can break the day. These are the timed entries on our plans that sell out or cannot be bought at the door:

• Anne Frank House, $18.50 (£13.90; €16.50): online only, released every Tuesday at 10 a.m. for six weeks ahead.
• Alcatraz, $48 (£36): on sale 90 days ahead. Closed for dock repairs from October 26, 2026, with reopening anticipated on November 19.
• Sagrada Família, $29 (£22; €26): online only, for a set entry time.
• The Colosseum, $20 (£15.10; €18): a fixed entry time you cannot change.
• Brunelleschi's dome in Florence, $34 (£25; €30): a named ticket with a timed climb, ID required.
• Edinburgh Castle, $31 (£24): timed tickets often sell out online.
• Shibuya Sky in Tokyo, $22 (£16.10; ¥3,400): sold up to two weeks ahead.
• Vienna's Kunsthistorisches Museum, $25 (£18.50; €22): every visit needs a time slot since September 8, 2026.
• Washington Monument, $1 (£0.70) online: released 30 days ahead at 10 a.m.
• Free but booked: the Reichstag dome in Berlin, the US Capitol tour and Preservation Hall in New Orleans, where every reservation is online.

Things change between booking and boarding. Our October 2026 checks picked up the Marché des Enfants Rouges in Paris, closed since a fire on the night of October 11-12; St Giles' Cathedral in Edinburgh, charging non-Scottish visitors since October 5; and Bruges's Groeningemuseum, which closes on January 11, 2027 for a four-year refurbishment. Dublin's Chester Beatty is closed until the end of December 2026. Check the attraction's own site, not a review page, a week out.

Pack for the walk, not the wardrobe. Our plans run 1.4 to 18.1 miles (2.3 to 29.2 km) between stops, much of it on foot, so shoes matter more than anything else in the bag. Bring a contactless bank card that works abroad: London, Nashville, San Diego and Miami cap a day of rides on contactless, so you never need to buy a ticket. Add a phone battery pack for maps and timed tickets, and a printed or offline copy of every booking reference.
