Park West is interesting.
The first V tour (2002) the venue was standing. The second V tour (2004) they had us seated, but it was still gen ad.
Your best bet is to call the box office a week to 10 days before the show and inquire, because they should know by then how V wants the setup done.
As for clarification, I'd say if you get to the venue by 3pm you should be near the front of the line if doors are at 6:30pm, although doors at Park West never open when they should, or at least they haven't in my two experiences there.
If you want to be safe, get there earlier. The bad news is even if you're in front of the line the way the venue is set up if people get in before or at the same time as you they could sprint ahead of you and get a better spot.
Did I mention I hate it when people sprint ahead after being back in line? :lol:
