We did this last year. The character interaction was fantastic. We saw Cinderella, the mice and Prince Charming. He was really great with the girls. Fiary Godmother sat on a chair and you went on line to take a picture with her.
The food was OK. Typical buffet food. Nothing that would scream out at you. They did have a very good selection, but I expected more desserts. They were kinda limited.
