Why wait for the AP rates? They may not be any better than the GP rates. For our last trip in January, I booked at the GP rate when it came out, and the AP rate wasn't any better when it did come out. I can also book the Florida Residents rates, and even those weren't any better than the GP. If you book now and the AP rate is better and available for the accommodations you want, you can always have it applied at that time.
