Yuck. I'm too old for roommates, except for my DH. I don't do bunkhouses, either. Sleeping in a mixed gender group setting with a bunch of strangers during my AMC leadership training sucked. I didn't sleep for 48 hours.
I like camping, but again, only with close friends, or family. And, frankly, I don't do so well with a large group of women, unless they are already people I know.
