I was at CRT for dinner on July 23rd. Before going up to the dining room, you meet cinderella and have your picture taken with her. There were alot of people waiting at the time and honestly my sister and I got about 2 minutes with Cinderella-we basically took the picture and they called us to go up to the dining room. However, I am 21yrs old and my sister is 17, so I can understand why Cinderella didn't devote that much time to us. At dinner, Ariel, Snow WHite, Sleeping Beauty, and Belle came around. They were really nice and we got pics/autographs. Then, towards the end of the dinner, a CM brings you several professional photos of the picture that you took earlier with Cinderella. We received several photos (not sure exactly of the sizes) as well as a picture of the castle.
CInderella does not come to the dining room, but I have heard that they rotate the princesses in the dining room. For instance, I think Jasmine is their some nights.
