I'm on the tried it once, it was OK, don't plan to do it again for awhile bandwagon. We had actually gone for breakfast and the food was good. Even though we were on the DDP, we chose to pay out of pocket for this meal (it made sense to us to use those 2 TS credit for a different meal instead of for one breakfast).
Little girls who are into princesses will think its cool, heck I thought it was neat enough, but I think it couldn't live up to the hype (the ADR is hard to get--it must be so awesome--everyone is doing it hype).
So, if you have never been & are interested in trying it--go for it. If you are on the fence about it or have trouble getting an ADR, then don't do it and don't feel bad about not doing it.
