The problem with siging her up as if she were a three year old is that you have to present a birth certificate or passport to board, and birthdates must match. IF not, they will deny you boarding. If you register her with her true birth date, you won't be able to signe her up for the kids clubs ahead of time. If they are not the right age, that option is greyed out on the menu. They will KNOW she is not yet 3, and assuming they are actually enforcing the age policy you won't be able to sign up onship either. If you don't go ahead and book nursery time, you may be completely out of luck. I would say count on her going to the nusery and hope to get her into the kids club.
