Hi
My DGD (5) loves getting dressed up. Two years ago, she wore a Cinderella costume to 1900 Park Fare, and last year she dressed in an Aurora costume for the princess lunch in Norway (PSB). Also, I bought her a Minnie Mouse costume that she wore to Chef Mickeys. Minnie paid so much attention to her it was really fun for her. This year she wants to wear a Jasmine costume, so I just bought her one through Disney shopping. We're hoping to get an ADR for the breakfast at CRT. So to answer you question, yes, a lot of the girls get dressed up, at least they were when we were there. Have a great time!!
