How can I ask her to share the bed without freaking her out?

For the last couple of weeks, I have been hanging out with this chick. We both like the same music and we go to a lot of concerts together. She's actually been to a lot of concerts that I was at but I didn't know who she was at the time. Next weekend her and I are going to a festival and staying with friends out of state. We are staying in their finished basement that includes a bedroom and a sectional couch. She told me that I could have the bed but a part of me wants to make a move and offer her to sleep with me in the bed. I wouldn't even be mad if we didn't have sex but it would definitely be nice to lay with somebody in bed together. How can I ask her in word it in a way that wouldn't freak her out
