We booked a room at AAA discount rates by calling WDW directly. I just called CRO and asked for the AAA rate for the resort, and time period, I wanted. They told me what it was. Sounded better than any other rates I could find so I booked it.
I matched the discount rates listed on the Mousesavers site. And, it was better than the rates quoted me by AAA. Since it was changing from value season to regular season during our stay AAA changed our rate, where as WDW kept us at the rate we checked in with (value season rate with the AAA discount).
