My seven year old attended last month (it was a Tuesday) and we didn't know what to expect beforehand either. You check your child in and are given a pager in case your child needs you while you are away. Then the moms wait for the doors to open and help their child find a seat. I could tell right away that Carly would love it. Flowers, confetti, and girly stuff everywhere! While my mother, son, and I ae lunch elsewhere in the hotel I saw two moms who brought their little girls together get paged. Their girls looked to be about three and Carly told me later they started crying when the Hatter came out. Make sure you are back on time because the kids have a surprise for you. Carly told me they had tiny turkey sandwich, chicken nuggets, strawberry sandwiches (she didn't touch) and had their dessert first. She truly had a wonderful time and I found myself thinking she was the perfect age for it. If your four year old is comfortable with the characters and being out of your sight for a short time (an hour goes by fast) then she should love it. Hope that helps.
