I don't really know the answer either. But I did book my upcoming trip through Disney using a AAA discount. When I called I told the CM I wanted to get AAA rates for first week of December on three different resorts and the various rooms within each of them. He was super helpful, I was on the phone with him for at least 20 mins deciding on what resort to stay at. The AAA rate is not available all the time and not for every room. Your best bet is to call.
