My DD turned 4 while we were at WDW last month. We had breakfast with Cindy and the princesses the very first morning and it was pure magic! (Walking down Main Street to the Castle with not another guest in sight was pretty cool, too). We saw Cindy, Snow White, Aurora, Belle (DD's favorite, who took the time to discuss with DD what Mrs. Potts and Chip were up to) and Mary Poppins. Fairy Godmother was downstairs when we left. DD was so excited that I was teary-eyed. The food and the service were both very good. We also did the Storybook Breakfast at Epcot. Although this was very good, too, it wasn't as special as breakfast in the castle. Characters there were Snow White, Belle, Jasmine, Mary Poppins and Aurora.
Also, after the show in front of the castle - which is every hour or so - alot of the characters make meet and greet appearances. DD met Suzie and Perla, and Prince Charming, among many others. This was great for a Cindy lover. Aside from the breakfasts and parades, we didn't see Cindy anywhere else in the parks.
