I think you'd be very lucky to get any kind of a discount during peak times such as Christmas. If you have AAA, go ahead and try to get your ressie on that discount. When they release AP discounts, call back and get the new discount if it is lower. We had an AP this past year but didn't get a better rate than using AAA. We went in January, May, and Christmas (stayed off-site as I couldn't get a ressie). I think I paid $35 per nite (on AAA) for a preferred hook up the year before in October and I paid more than that in January and May which I think were both value seasons as well (used my AP)
