I'm in WDW now and attended the party on 6/17. I had 2 DD's with me, 6 and 11. I paid the adult price for the 11 yr. old because I didn't think she needed the doll.
They are still working out some of the kinks, but I thought it was very nice. There were about 15 girls when we were there. Everyone had a pre-assigned table, which made it very orderly.
My only negative comment, would be the food. I did notice that not many people ate, and I think that this has been a concern because we were each asked about the choice of food.
The "princesses" are served peanut butter/jelly tea sandwiches and ham/cheese tea sandwiches with grapes and apple juice, Most of them were too excited to eat. The adults were served chicken salad, egg salad and salmon sandwiches with grapes and tea, as well as some slices of hard cheese and crackers. Unfortunately I don't like onions and each of the salads contained onions. Not a problem, as the menu was not why I chose to go. However, not many ate and the cast members were looking for feedback.
They also served strawberry shortcake which was very good.
Any further questions, let me know.
Thanks!
