You know, it is so hard to tell what the rates will be this far in advance. Sometimes, during seasons when it is supposed to be very busy, the AP hotel rates suddenly dip lower than I expect (like last December, for example - that was the peak holiday season, but the 3 DLR hotels were NOT booked up, and there were some fantastic AP rates for that time of year, the weekend before Christmas; I was shocked), and other times when I think they will not be TOO high, they are ridiculously high. The early part of January will still be considered the "holiday season." I know that by February, it is considered off-peak. So somewhere in there the rates should drop a bit. But you won't get the concrete rate info until probably October.
You can always book something through the AP reservations number and put down a one night deposit now for what they estimate the January rate will be (in their computer, I suppose), and they will apply the standard AP 10% discount. Then, if a special 'AP rate' comes along for that month (which you will know in October), you call the reservation number and switch your reservation to the lower AP rate and they will do it with no problem. Last year I had those poor Cast Members switching so many things around in my reservation, trying to get the best deal! Just make sure you get your AP before you check in to the hotel!
