If there are any good hotel discounts this year, either available to AP holders or to the general public -- and I think there probably will be, as there is usually some sort of hotel discount each year (with the exception of 2012) -- I would expect it to come out after the summer season ends.
There have often been discounts that included a large chunk of Fall, like maybe from late September/early October, all the way up to mid-December or stopping on the last day of the weekend before Christmas -- and skipping certain busy times like Thanksgiving week or Veterans Day weekend, Columbus Day weekend, etc. I would expect that maybe something like that would come out again this year -- but it is anyone's guess how much of a discount there would be. Sometimes it could be 25% or 30% off of the hotel rate. Sometimes it might be 20%.
