Under 3's go free with a paid adult ticket.
All guests require a valid ticket to enter, most ticket types give the option to purchase an under 3 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 prior to checkout.
If you did not have the option to add an under 3 ticket during your main booking, please click here to reserve a ticket for them, which is essential.
