Here are the details for AAA discounts at the resorts as found on another website...
"AAA and CAA Resort Hotel Discounts
American Automobile Association (AAA) and Canadian Automobile Association (CAA) members qualify for "room only" discounts almost year-round, though there are a limited number of rooms available for each date. You can generally save about 10-20% at the Disney resort hotels, depending on the season.
The 2009 discounts seem to run as follows:
* Value Season: 15% off at Value, Deluxe and Deluxe Villa (Disney Vacation Club) resorts; 20% off at Moderate resorts and Ft. Wilderness cabins and campsites.
* Regular Season: 10% off at the Deluxe and Deluxe Villa (Disney Vacation Club) resorts; 10%-15% off at Value and Moderate resorts and Ft. Wilderness cabins and campsites.
* Peak Season and Summer Season: 10% off at all resorts.
The only time AAA/CAA discounts don't usually apply is Holiday Season (around Christmas).
You don't have to book AAA/CAA rates through the Auto Club. Room-only reservations with an AAA discount can be booked directly through the Disney Reservation Center at (407) W-DISNEY or a
travel agent who specializes in Disney travel. Just ask if there is an AAA or CAA discount for your dates and resort.
AAA/CAA rates for all of the following year are usually released in the summer. 2009 AAA/CAA "room only" discounts were released on August 3, 2008."
