Frequently asked questions
What is the number one thing to do in London?
Tower of London & Crown Jewels — skip-the-line entry with a Yeoman Warder tour is the standard move. Start there, then build the itinerary around it.
Do I need to book London attractions in advance?
The headline attractions reward advance booking — timed-entry systems and quota tickets mean walk-up availability is worst exactly when you want to visit. Everything on this page links to providers showing live availability.
How many days do you need in London?
Three to four days covers the shortlist above at a humane pace for a first visit; add days for the day-trip formats rather than compressing the city itself.
Is a city pass worth it in London?
Run the arithmetic honestly: a pass wins when you would genuinely visit three-plus ticketed attractions in its window. Our provider links show pass options side by side with single tickets — compare before committing.
