Top at summer camp when I was a camper, and when I was a counselor. I liked it, although as a counselor, what I would do is hang towels and my other set of sheets down from the rafters to create my own private space. Eventually, we were told by the higher-ups that we could only do this for our one day off a week, because something about wanting us to be aware of the kids during the night. Of course, inevitably on my one day off, I'd hang the sheets up, and someone would ignore it and try to wake me up because they weren't aware it was my day off.
Only time I had a bunk bed in college was my sophomore year. I had the top for the first semester, and didn't mind it, although my roommate and his girl would do certain things in the bottom bunk. He usually slept over in his girl's bed (which was next door; yes, we were neighbors), and eventually I decided that since he rarely was there, that I wanted the bottom bunk. It took a couple of weeks, but he finally agreed.
