Seem to recall a similar statement in the rules for staying at Cranfield University's Dorms, however no one paid any attention to them. Several people in multiple rooms on a very regular basis, and not just from the CabAir clan (fortunately). Shame this old fashioned attitude of (flying) schools still exists. Let's face it, they trust us after a year or so to fly a $50 million+ aircraft, but we can't have friends over when we want to. Does this not seem odd to anyone else?
