ah. this question reminds me of a detail I was told just the other day, but have forgotten to put it here (sorry guys). now, don't take this as a guaranteed or confirmed thing, but as far as I've heard, the car park will stay open, even when the music eventually stops. so apparently the bars will stay open, obviously the toilets as well. this should take a lot of the inside pressure away I think. if you need a breather (or a toilet visit or a round of drinks), just head out to the car park. if this is true, then it's a massive improvement and will help this closing to be bearable! at least that's what I think.
WOOOOW a BIG camping AREA. We just need a soundsystem to camp and rave there after the music ends. Space resistance!
