I have been thinking about that, as have a lot of others. If I had to guess, I would say that around mid-August, they will release an AP code through December 19th. I would say that since the Best Rate Program has been so popular (there are hardly any rooms left at most resorts through 12/19 if you play with the website), there will be a very limited number of rooms released with the announced code. I would also guess that the announced code rates will not be any cheaper than the best rate prices. However, if they are lower and the best rates that have already been booked are not changed to reflect the lower rates, Disney is going to get a lot of wicked emails. There is another thread below talking about that.
So, I guess we will all have to wait and see what happens! I hope I am wrong because I know there are a lot of AP holders who missed the 120 day window for the Best Rate Program and I would hate to see them not get a discount.
