One things to remember is that the Norway Akershus breakfast (Princess Storybook Breakfast) does NOT have Cinderella but just about every other princess rotates being there. My 3 yr old DD was a Cinderella NUT when we went down. The second day there we went to this breakfast and saw Mary Poppins, Mulan, Jasmine, Sleeping Beauty, and Belle. The food was great and the princesses and nanny were wonderful!!!! We still had to find Cinderella and my daughter did get very excited when we found her (see below), but when all was said and done, Jasmine is now her favorite and the doll she had to bring home from Disney because of the breakfast. Wouldn't have missed getting to meet all of them in one place for anything. It was worth the money even without the food which, again, was great in our opinion.
As far as finding Cindy - we asked one of the CM's standing in front of the castle's stage when we could find Cinderella and she told us that as soon as the 10:45 show (not sure if this will change with the new Cinderella show or now) was over that she went directly to the big tent in Toontown as mentioned above. Well, we timed it correctly and she was indeed there - along with Prince Charming. It was wonderful! My suggestion - ask those CMs - some of them are a wealth of info...
