Hey now. That's one of the reasons why my wife and I throw down the extra funds - to avoid the lines underneath the arch. If there is no designated VIP entrance/exit, I predict a lot of people in VIP are gonna be pissed.
Yeah, this was a huge thing with me at the VIP tollbooth last year. The parking attendant that I got into it with was telling me that there was no special entrance, when ACTUALLY, they just keep the wall closed off until noon-ish on Thursday. I'd be really surprised if we don't have our normal two entrances - one by the arch and one at the main stage.
I remember watching them remove part of the wall from my campsite around noon-ish thursday last year and yelling that they are opening vip entrance loud enough for several campsites to look up.
This was very fun to watch. Bunch of guys with saws, and other tools, just show up and start tearing down a section of wall. It made me feel just a little bit special to see a crew cut an entrance into the wall just for us!
