We were there last Thursday. There were Fantasmic showings at 9:00 and 10:30. We arrived at 6:00pm and there were a lot of people milling around waiting for the characters. Sure enough, at 6:10pm they showed up. We had time to meet Captain Hook, Belle in her blue dress, Max, Mary Poppins, and Aladdin. Also there that night were the green army men (3 of them), the Queen of Hearts, Pocahontas, Pinnochio, and (IIRC) Minnie. It's possible I'm forgetting some of the characters that were there.
It was DD's favorite part of HS and that's saying a lot because she LOVES Fantasmic.
