I actually put my 2 sons into it last year, at the time it was the only thing offered for 3 year olds (it is now 4)
Anyway, they LOVED it! My older boy was almost 6 and did not want to go, but loved it. They even would like to go back again.
They have tea (apple juice) and cupcakes before lunch.
They play games with Alice and the Mad Hatter like hide and seek and duck duck goose.
My husband and I went to have lunch down the hall at the GF cafe....plenty of time, nice and close and it was a nice breather!
I am thinking of booking this for my 9 year old daughter. She is a young 9 year old and I think she will like it. Is it worth missing park time and the cost?
Our 6 yr old did this in January and had a blast. She says it's a must for each trip now. (It also gives them a chance to fill "grown-up" since their parents aren't allowed to be in the room.)
They'll give you a keepsake photo of your child and the characters.
