can someone please explain how the universal gift cards work? saw them at my local grocery store and they say can be used for ticket media or exchanged for universal dollars at a ticket counter. is it worth the fuelperks i will get or is it a hassle?? can i exchange them at the hrh or does it have to be at a ticket counter at one of the parks? will already have tix and dont really want to stand in another line!! one more question--can the universal dollars be used in conjuction with aaa discount?? thanks!
