Yes, Pooh, Tigger, Eeyore, and Piglet are at the character lunch. The buffet is my family's absolute favorite. We always do this lunch on our first day--we even try to get in a second lunch there later in the week if the schedule allows!
The buffet features fresh salads, breads, carved meats, side dishes and vegetables, a kids buffet with pizza, mac & cheese, and chicken tenders, as well as a dessert buffet with ice cream and freshly baked cookies.
We have always had good interaction with the characters here and usually at some point, they start the music and the kids can join in a parade around the restaurant. I think your DD will love the characters here, and the food is, IMHO, delicious!
