ok so ive been lucky enough to get tickets at a fair price... we were going to go with another group but they want to leave at 7am (from AZ) to get their b4 gates open and we cant leave until 3pm that day we dont have a camping pass and were going to go with them ... if we drive our car down there is there any place to leave it??? hotels? valets? Wal-mart? idk any ideas or suggestions?
