Visiting my "friend"

So this weekend I'm going to be going to my visit my friend at his college. I'm staying in the dorm with him and I've never lived in a dorm or stayed with a guy I'm not seriously dating. Is there anything I should make sure I bring? I wanna look cute but not too high maintenance and I'll be staying in his room, we've been friends for years and have hooked up a few times but we both want it to be more than that. Any tips?
