I got one in May when I purchased my DD's park tickets thru AAA. Although my name was not printed on it, there was a spot for name. Parking attendants are within every right to make sure the name on the pass matches your identification. I would be too afraid one of the passes already had a name on it and I would have just wasted my money. We always got to a park early and had no problem getting one of the spaces. At MK, this was AWESOME! We have small children and a stroller. Instread of trying to fit all of us and the stroller on the tram we just walked to the monorail. At the end of the night, with a sleeping toddler, we just had to walk to the car and put her in her car seat and she slept right thru. Now, if we had to take her out of the stroller to get on the tram, and then carry he to the car asleep that wouldn't have been too convenient. They are non transferable as a PP mentioned. If you obtain one thru your AAA office, they are actually good for the year. For example, I am using my pass from May for our trip in December as well.
Good luck.
