Once
This happened to me once.
I work in the financial services industry, and there were times when inclement weather would result in my employer making last minute decisions to put up several staff members in hotels in order to insure that we would be able to report to the office the next day.
Once, four of us (all males) bunked together in one room with two double beds. This was in the company's conference center, which is attached to the office. We were all in our early to mid 20's, so none of us had a problem with it, but thinking back on it now, it was a bit cramped.
