I did my first Wacken this year and will highly recommend having someone else do your set-up. For camping check out Ready-to-rock. They are awesome and nothing beats not having to set up a tent or take one down when you get there/leave. Arriving to a fully set up tent was great! Also, if you use them you get to be in a nice location which is also more quiet than the 'main' campgrounds and also closer to the stages
Yeah, I've been checking that out, looks exactly what I want! Cheers much
