Our must haves for festivals are tarps - because it will rain at some point during the weekend and they are so versatile. Use as a shelter, to cover the ground so you're not in mud at your site, under the tent, even as a poncho...I buy a bunch to bring along with me because you can buy them super cheap (dollar store has them) and you can share with neighbors who haven't planned for rain.
