When I booked my room at the PPH yesterday I was told by the reservation agent that helped me that AP rates come out 2-3 months prior to the actual date that you are going to stay there. For example I booked a room for July. The agent told me to check back in May for the AP rates and then to call them back and she will adjust my rate. But she also said that because this year is Disneyland's 60th anniversary, to book all rooms ASAP and they can always change the rate when the new AP prices come out.
