It depends on where in line you are.
The line inches along,but it's a slow process.
I would guess,if you get there Thurs.am.you will get settled in by the afternoon.Only a guess.could be sooner.
As for tix,I always got the all fest w/camping.
That used to cover vehicle also,but many things have changed over the years.

I admittedly used to gripe about the long lines to get in,but I always enjoyed myself once I got settled in & started playing music.

Enjoy.
