do you need a separate wrist band or something to get on to the camp grounds?
no coachella for me this year. lineup is too weak to fly coast to coast.
From the Camping FAQ:
Can I bring my friends into camp?
Sure, as long as everyone has a festival ticket you can have them come to your camping spot.
I didnt camp last year but in 08 anyone could visit the camp grounds during the day but at night they check wristbands..
I think you might be able to re enter if you go through the security check again
