We used ours everyday. We decided not to use the hotel bus system (we stayed at POR) and just drove. We were no more than 10 min. to any park pretty much. The AAA pass puts you around the handicap area of each lot. You'd kind of think they would be right in front, but they aren't necessarily. At MK they are off to the right of the entrance and a fair walk. Depending on when you arrive at the park it can be better than first come first serve. I tihnk we'd drive again just to have the convenience of having our car there and not waiting for any busses.
