here's our list from this past January of the different parks characters we met. (i had listed the characters on the front page of my dd autograph book with the park we met them at - if you do autographs it's a good idea because some of them are hard to make out after awhile.)
Animal Kingdom:
Mickey, Minnie, Goofy, Baloo, King Louie, Flik, Timon, Stanley, Lilo, Stitch, Pluto, Suzy, Perla. We also saw DiVine, Pochantos, and the character from Brother Bear but didn't get autographs.
Epcot:
Genie, Belle, Beast. We also saw - but no autographs - Nemo and the Living Seas, Imagium Statue, tons of street performers
MGM:
Chip, Dale, Donald Duck, Tigger, Piglet, Eeyore, Woody, Buzz, Jessie, Kermit. Mickey, Minnie, Goofy, Lilo and Stitch were there also.
MK:
Mickey(different outfit), Daisy Duck, TweedleDee, TweedleDum, Robin Hood, Meeko, Captain Hook, Mr. Smee, Princess Aurora, Cinderella, Pinnochio, Gepetto. We also saw many more signing autographs but we didn't get autographs from including: the white rabbit, other characters from Pinocchio and Robin Hood, Peter Pan an Wendy, Winnie the Pooh, etc.
now keep in mind we really didn't search out anyone in particular except at Toontown and AK camp. So I think we did pretty good. I heard there were other characters in Epcot, but like I said we weren't specifically looking all the time.
