I purchased park hoppers from AAA for my upcoming trip. I would like to upgrade to AAA to get the AP discount. I had read a previous post about looking at the back of the pass for a $amount, but I don't see anything like this on these passes. They look like passes I have had in the past on the front. They do have a date on them which is I guess the date when AAA purchased them(12-01-00). <IMG SRC="/infopop/emoticons/icon_confused.gif" alt="confused">
