I can confirm that the Swan and Dolphin do discount all of their suites (with exception of presidential suites) the same as they discount other rooms (e.g., AAA). We are staying in a 2 BR Executive Suite at the Dolphin and obtained a AAA rate on it - normally $1200/night, but able to get it for approx. 50% off.
I know that there are debates about the "Disney-ness" of these resorts, but IMO you would never know they weren't "true" Disney hotels, and any "magic" that you lose is more than made up for by being able to earn/redeem Starwood Preferred Guest points and to get terrific room discounts the other Deluxe Disney resorts can't touch.
