Living in college dorms was a fun experience. You'll always have company, even though sharing bathrooms sucks. Lots of late nights and lots of partying. I wasn't a big fan of having roommates simply because I kept different hours than both of my roomies and they were both major homebodies who didn't like to go out and socialize.
It also made having sex a pain.
I had a single room my junior and senior year of college...that was awesome
One important thing that college will teach you is how to be responsible. If you don't want to go to class, you can choose not to. If you don't want to do your laundry, you can walk around in dirty pjs. Definitely forces you to learn how to depend on yourself.
