@Britsmum, no regrets at all. In fact, she only took the single because it was still in the substance free dorms. D isn’t very social so that’s not an issue but she is very anti-drugs and alcohol (yeah, not a great stance at college, lol) so it works for her.
Remember, the campus is small and its easy to get around. I don’t think there’s really that much difference where you reside quite honestly but substance free = quieter and that’s a big sell for students who are really studious and/or need a lot of quiet time for whatever reason.
