Edit: I've just counted the hours during which I was partying at the main stage. Didn't really see anything other that mainstage. Walked around the terrain the first day but other than that there weren't really artists playing at the other stages that I really wanted to see.
Friday: 7h15min nonstop at mainstage
Saturday: 9h nonstop at mainstage
Sunday: 6h30min nonstop at mainstage
Red Bull helped, but really I can party waaaay longer when I'm sober than when I'm drunk.
Oh and check out this awesomeness
I'm prolly somewhere in that pic.
