Easy non-heat hairstyles?

I'm going camping next week for 6 days, and I won't have access to electricity. I usually straighten or curl my hair, or I use styling products. My natural hair is slightly curly and 'fluffy' in an awkward way. It's about 3 inches past my shoulders and really thick. What are some quick, easy ways I could style my hair without any hair products? I know it's kind of pathetic to worry about hair while camping, but I'm going to be around all of my friends, and I really don't like wearing my hair completely natural. Thanks!!
