The college I went to is more of a commuter college so I didn't have the dorm experience, but the general feeling I get from people who did is that if you have good friends/roommates it is an awesome experience, if not it will kind of suck, especially if you are farther from home and your home friends.
The best advice I can give about college is just be yourself. It is a whole different world than high school, which I was very happy about :lol:.
