Cerb,
If you are planning on buying tickets at the window with a pepsi can (like i am), plan on a good wait in line if you get there after 6...i waited 15 minutes in line to get my will call tickets. And, traffic is a mess. Plus good tickets go fast when you are waiting in line for that long.
Of course if you have tickets already in hand, disregard what i said
I'm planning on getting there as early as possible. I might leave my house around 4'ish (I live an hour away), to beat the Skyway construction traffic. Any clue on what time the paid parking lots open? I'd hope a bit before the gates open.
Lots are supposed to open two hours early, but sometimes for big crowds they do open earlier. I would call 674-1000 and ask them.
