Lunar New Year Weekend had Mickey, Minnie, Chip, Dale, Mulan and Mushu
And Mardi Gras was in New Orleans square, unlike the rest. It was in two parts. One was Tiana, Naveen, Louie and some other New Orleans themed performers doing a little show with some singing and dancing then the other part had Mickey, Minnie, Donald, Goofy, Chip and Dale.
Each event had other stuff going on too. Like the Character Fan days had artists and they would draw characters for you. Others had musical performers and dancers. The one I went to was alot of fun and I hope they bring them back next year.
I might have missed afew characters out, I'm just going from memory
