You can only select a time slot for the attraction you buy the combination tickets from - in our case Madame Tussauds London.
You will receive tickets for the other attractions when visiting Madame Tussauds London, which you can then exchange at the attractions. At Shrek's Adventure! London, The London Dungeon, The Coca Cola London Eye and SEA LIFE London they will book you into the next available time slot/show time when you arrive at the attraction. Alternatively, when you collecting your tickets from Madame Tussauds London, our admissions team will be happy to advise of the remaining availability for our other London attractions and book you in, subject to availability. Please note entry at any given time or day is subject to availability and pre-booking is not possible over the phone or online.
Don't forget you have 90 days to use your combination tickets after the first date of use.
