in other discounts beyond just the obvious towing. Discounts to other theme parks, 10% at payless, dining discounts at various restaurants (always ask you never know), hotel discounts, airline and car rental discounts. If you prebuy at your aaa office, discounts for movies, tourist attractions, county fairs, etc. Places that don't give that at the gate, give them if you buy on their website or local office (ie baltimore acquarium saved us $8/pp ahead of time over the gate price. Casual corner 15% and some days its 20% off. The key is ALWAYS ask for a AAA discount. Plus you can get great car insurance, homeowners insurance rates, things like that. I have AAA plus which costs more, but its worth to me for the 100 miles of free towing, free travelers checks, free travel books and various other services. I always get my $72 back every year (yes it expires annually). Ask your company if they offer group discounts for membership, I work for the gov't and my 72 for family rate is vs 88 that we'd pay if I didn't work for them.
As to discounted rates its anywhere from 10 to 20% off at WDW resorts based on value, mod and deluxe and the season you are going in. You don't need a card number to ask, just to book, and sometimes they only need the number to check in if you tell them you'll have it by check in.
