I think all of them are great, even for parties of adults only!
My DH is a big stinker and refuses to attend character meals unless the characters can talk back so we are severely limited in our choices =) That said, I twisted his arm into 1900 Park Fare (it has 2 non speaking characters) and he dealt with it. I love Mary Poppins and Alice and the Mad Hatter are fabulous!!
Our other favorite breakfast is Princess Storybook in Norway. We love seeing all the princesses at once, DH especially loves Jasmine, and the food is pretty good. We took my father in law and 70+ year old great uncle to it in Sept and they both quite enjoyed themselves =)
