I agree, if your 90 day window is already open, you are probably in a take what you can get situation. Cinderella's Royal Table will probably already be booked solid, and Chef Mickey's is a long shot, especially for breakfast. Between the two, my DD would pick Cinderella's just because of the Princesses. It really just depends on what characters you want to see. I don't think you can go wront with either one. I agree if you are too late to get either of those that Crystal Palace with Pooh and Friends would be a good alternative.
