They go at their own pace out there. So I would just keep checking. I cannot remember when I booked dessert party for July.... but less than 60 days. It was not terribly hard to book, and I went on the week of D23.
I LOVED the WoC dessert party, well worth it for us. Not for the local AP holder, of course. But great for guests who go once a year, or every other year. PS if it says line up at 8:15, or whatever, line up earlier. We went for the front row high top table, and I think that is the way to go. We got one of the last couple of these that were left, and we sat almost all the way over on the left side, facing the show. This had us in what felt like dead center, did not feel like we were on the side when show started.
Just realized you did not mean the dessert party, you meant a meal WoC package? Ooops. We picked the Dessert Party to get comfortable seating for the show.
