I wish I could tell you how many times a week we get asked this question. And that makes total sense because the process for booking dessert parties has gotten pretty confusing in recent years. Disney publicizes that the dessert parties open up for booking at 180 days (like dining reservations) and while that may be true sometimes, it definitely isn't true ALL of the time. In fact, more often than not you'll find that those pesky dessert parties don't open up at 180 days. Or even at 90 days. Sometimes they don't even open up at 60 days. And, there really isn't any rhyme or reason to it. Well, at least not to "us" non-Disney employed folks there isn't.
