You may exit the festival & re-enter as you wish. BUT, if you are car camping you MAY NOT exit with your car from your campsite & return to your campsite in your car. If you leave (with your car) from your campsite, you will be directed to park in day parking upon your return & then must find your way back to your campsite. We highly recommend bringing everything you need for all 4 days so you do not need to leave. If you plan to stay in a hotel or somewhere else off site, you may park in day parking each day when you arrive and leave at your leisure.
