The first 3-4 years I went (2004, 2005, 2007, 2008) there was only Lost Vagueness down there, but tbh most people just went back to their camp after the headliners and had a fire till the small hours and went to bed.
The last time we had a proper campfire in our group was 2008! Its a 24-hour party now and this year one night I went back to our camp at 3am to get a jumper and it was a ghost town...everyone was out and about!
I didn't find it overcrowded this year tbh, I found more issues with the stages/bars/food stalls during the day.
