Presuming you have a full weekend ticket, there are no restrictions on where you can camp in the normal fields. Campervans however will have to park up in WHITE camp. VIP have their own camp. Other than that, the rest of us humans have every other camp to mess around with. If you have 'X' car parking pass, that doesn't mean you have to camp in 'X' coloured camp. You are free to roam about all you want. No restrictions on going from camp to camp.
