It's JMHO, but I think Disney has adjusted to the fact that many people are now waiting until closer to their arrival date to book their hotel stays.
Before 9/11, many people booked way in advance - up to a year or more. Disney wants to maximize profits - can't really blame a business for that. If they think their hotel rooms will fill up without offering discounts, they have little incentive to offer them, especially several months in advance. I think there will be some discounts (both code and AP) offered for the summer, but I think we will have to wait a while longer to see them. Good luck to all who are waiting.
