I see on AAA's website that you get a 10% discount at "most of the 100 shops/restaurants in Universal parks and CityWalk". We are AAA members and are planning on spending a day or two at Universal/IoA. We're eating lunch at Mythos and I'm sure will purchase a few things around the park(s). Is it generally everywhere you can get the 10% discount or is it far and few between? Thanks for any help!
