When we were there a couple years ago we had the picture with Belle in her gown, then Mulan, SW, SB, and Jasmine came around our table. They were so awesome with our girls. I really would love to see Aeriel in her gown because that is my youngest's favorite princess, but I think she is only there for dinner as a greeter and we are going for breakfast again.
As for CRT, the last time we were there was back in 2005 and we had the Fairy Godmother as our greeter downstairs, then we had Cinderella, SW, SB, and Mary Poppins coming around our table. There I felt rushed by the princesses, they only came to the table to take the picture and sign autographs, they really didn't interact with our girls....this was the first time my girls were at Disney and this was the 1st character meal of the trip, but the girls still loved it because they were in the castle and there were Princesses.
