I did the stumble back from District 9 twice and it's not as bad as it looks. It took about 20-30 minutes once I left the campground I think, and is more fun with friends than solo.
Everybody kind of has their own little parties with their group, but it's generally pretty quiet after all the shows are over. We got a talking to last year after we were pretty loud the first night (and were caught peeing in between cars) but had no problems after that, and that's with a 'nater and a megatron in the group.
Just fer yer info, the shuttle doesn't drop you right in front, it will drop you kind of at the edge of the parking lot.
Man, even as a (gulp....admitting some serious shit here) self-avowed kinda Miley fan (I'M SORRY BUT THE MORE I LISTEN TO MUSIC THE WORSE MY TASTE GETS) I can't even watch this shit. That is embarrassingly terrible.
