IF there are Ap rates they should be coming out the end of Aug. Last year it was Aug. 25th or Aug. 28th one was for FL the other Ap rates can't remember which dates for which. Also from what I have read that the break even point on purchasing an Ap just for the hotel discount is about 8 days so unless you are planning on visiting again within the coming year it may not be worth your while to purchase an AP.
I don't know your location but if you are a FL resident the seasonal annual pass is a great deal also, all the benefits of a regular AP other than some blackout dates and alot cheaper.
