We have done both several times. We far prefer CRT. There is just something special about eating in the castle. The girls get wands and the boys get swords. That said, she will love either one because they both have Princesses. If Belle is a favorite, she will get a formal picture with her in her gold dress at Akersus. Occasionally if something happens, Belle has a substitute, but she is there probably 95% of the time. I don't know if you plan on doing autograph books at her age (DD didn't until she was a year or two older than that), but if you do, that is the only place she signs in her gold dress. She is out in WS in her blue dress and signs there. There is no place in MK anymore where she signs or where you can have a conversation with her- ETWB is is just an extremely rushed photopass pic. Ariel usually makes a table rotation both places. Rapunzel doesn't usually appear at meals, but I hear lately she has been showing up at CRT here and there.
