I've been looking for a Wishes dessert party for the same day! Just started planning a last minute trip about 2 weeks ago. I wanted to get a BOG for our MK day so I was looking from time to time the first week. Last week I started checking more frequently and what do you know, a BOG ressie for 8:55pm came up! I was so excited but now I'm trying to look for an earlier time so that we could try and get a ressie for the dessert party.
Aww well I hope you find one!! I am still looking for BOG everyday... I really want 8/29 because it's my birthday!!! But I will take any day! I have a theory that they periodically release more reservations. I know our last two trips we didnt get one until a couple of weeks before we left... And there were lots available... Where before there were none! If we can't score a dinner that works, will have to just do lunch! Good luck!!!

to a 'cast member' at the dinner reservations a few weeks ago and she said the update the reservations every morning at 6 a.m. est. for over night and over seas cancellations.
We're going back in a three weeks and we were just there in early June!!!
We had to change our plans about 2 months ago and lost most of our ADR's. Since then I have been checking 100's of times a day and checking cancelation threads. Ohana came pretty quickly, BOG took about a month or so but finally got that, for an even better time. The only one I needed was CP @ RD
Persistence does pay off and thanks to whoever cancelled.
