When arriving at the festival you exchange your ticket to an armband/bracelet which gives you access to both the camping area, and the stage area.
Many people show up a week before the music starts to get their tents up so they can sleep close to the stage area, and limit walking as much as possible as the camping area is huge! A good tip is securing a place as far from trees and fences as possible, since they in essence become one big urinal during the festival, if rain is forecast, you should also attempt to camp as far from the marked walkways, preferably on a slope, since mud quickly becomes and issue.
