If a date is appearing as greyed out, this will either be due to restrictions on one of the Passes being used to book, the attraction being closed or the attraction you intend to book is sold out for that specific date. If you have checked the relevant restrictions calendar for your Pass and the date is not greyed out, but day tickets are still available for purchase, please contact the Merlin Annual Pass Contact Centre to inform us and we can investigate into the attraction’s availability.
