I'd say breakfast or lunch at Cinderella's Royal Table at the castle if you can get an ADR. If not, Akershus in Norway at Epcot is a good substitute. My DD was 2 at her 1st trip, the only princess she was crazy about pre-trip was Cinderella, BUT we took her to Akershus and ever since she has been all Princess, all the time. At 3 this May, we took her to CRT and she loved it. She was very impressed with actually being in the castle.
