Going to Cindy's Gala Feast - what to expect?

[viluvsdisney]

HI - we got our PS to 1900 Park Fair for Cinderella's Gala Feast - never been before. My DD is 4 and very excited She wants to know all about it - but not sure what else to tell her other than Cinderella will be there (and perhaps the Fairy Godmother). Please tell me all you have to know about this character meal. Thanks!
