Epcot Breakfast
Pros - easy to obtain, there are set seating times, plenty of room to roam about while waiting
Cons - setting just doesn't seem 'royal' enough at Norway, some of norway is under refurbishment which wasn't pleasing to the eye, once the princesses left our area we were unable to see them, when breakfast was over there didn't seem to be a perk in being in the countries early and some parts were closed off.
August Characters - Jasmine, Mary Poppins, Aurora, Belle, Snow White
Cindy's
Pros - food is better (IMHO), castle setting fits well, you are able to see the princesses most of the time during the meal even if you aren't interacting with a princess due to round shape of dining room, early PS gets you into the MK for opening which can ease wait for a major attraction
cons - hard to obtain PS, the wait can be long, waiting does not allow as much freedom to move as Epcot
June Characters - Cinderella, Belle, Mary Poppins, Prince Charming, Snow White (in waiting area)
December - Cinderella, Belle, Mary Poppins, Snow Prince, Snow White. Aurora, Fairy God Mother (in waiting area)
