I don't think there is a general show your AAA card and get as discount anymore. If you buy Universal tickets through AAA, you can get a discount card for some dining and merchandise though. From Mousesavers -
Members of the American Automobile Association (AAA) or the Canadian Automobile Association (CAA)
save 10% at select dining and merchandise locations.
Note that as of April 2015, we are hearing that Universal is requiring guests to show a special “Discounts & Rewards” voucher along with their membership card. You receive the voucher from participating AAA clubs when you buy tickets or a vacation package from AAA. It still may be worth asking for a AAA discount even if you don’t have the voucher, especially at independent restaurants like Margaritaville and Hard Rock Cafe.
- 10% off select locations in the two theme parks. (Offer excludes merchandise or food carts, tattoos, alcohol, tobacco, candy, film, collectibles and sundry items.) If you belong to AAA or CAA, be sure to ask at every theme park restaurant and shop whether there is a discount.
- 10% off Universal Orlando CityWalk restaurants and shops. (Offer excludes merchandise or food carts, tattoos, alcohol, tobacco, candy, film, collectibles or sundry items. Discount on food, non-alcoholic drinks and merchandise at all CityWalk restaurants and shops with the exception of Emeril’s, Bubba Gump, Fossil and Fresh Produce.) Valid up to six people per AAA membership card. Show your membership card to get the discount.
