Under 2's go free with a paid adult ticket.
All guests require a valid ticket to enter; most ticket types give the option to add a free under 2 ticket, either whilst selecting the number of Adults and Children, or after you have selected the date and time of your booking. These will add to your basket before checkout.
If you are unable to book a ticket for your under 2 in advance, please do not worry. Please talk to a member of staff upon your arrival, and they will be able to issue you an additional ticket for your little one.
