Have just called the Wach again - this time the woman answering the phone knew that there would be two GA lines, and said "they will be distributing wristbands at 6" - when pressed, she said "for the GA line"
Basically, the lot opens at 12 for parking and security will know everything. I feel so much better not having GAs this time around.
Everyone - best of luck! I'm getting there at 4:30 to hang out before the show - if you see a red prizm with a bunch of people nearby, stop and say "Hi Phyllis!"
p.s. - the Wach's number - 215-336-3600
Love their level of unpreparedness!
