Hi
I followed the tips on the restaurant forum. Start calling at 6:55am EST exactly 60 days out and listen to the Sorry Disney dining is closed. Keep hitting redial until you hear the message "all CM's are busy etc"hold on until you get a live person. I've gotten it twice, last yr ,and for our next trip by just saying Cinderellas for 4 anytime, most CM's know why you're calling. The last CM I had saw it as a personal challenge to "get that PS". If you specify a time it's a lot harder to get.
BTW my DD who's 51/2, loved it. (but then her whole room is the princesses -by her request- and when we visit WDW she tells everyone she's going to visit the "other" princesses.....
