The current AP rates, if similar to the code rates, will probably have to be booked by the end of September for rates through the end of the year. Not sure on this...AP rates could be available much longer than codes and I haven't seen an expiration date or "book by" date for APs . I wouldn't count on the rates being available anytime soon. Even before 2001, I don't think they released AP rates very far in advance. I think beginning of November is probably when you'll see January rates. But this is pure conjecture at this point since no one really knows.
If you know you want to go in January, I'd book a room now so you know you have a spot at the resort you want and then change to AP rates if they come out later.
