Cinderella does not mingle at CRT-as stated above she is just there for the main photo. Princesses are there for brft and lunch, but not for dinner(only fairy godmother and mice, maybe?) 1900 PF dinner has Cindy, Prince Charming, step-sisters & mother, who all mingle (brft is different charac.) At Askershus in Epcot, Cindy does sometimes make an appearance, and will mingle there (as pics are w/ Belle or Aurora), but it is never guarenteed. If she is most important to your girls, CRT or 1900 PF are your options. I recommend the castle for atmosphere(very magical) and getting to see the main princesses all at once(we had Jasmine, SB, SW, & Belle(blue dress), and get autogr./pics out of the way so don't hunt for later. We had brft and thought it was good. Also if you can get early reserv., you can enter the park before RD and get castle pics w/ no one around! Allears.net will give you menus of each, w/times, prices, and charac. Good luck!
