It's fun as long as they don't overstay their welcome; I still recall the horror story told by a female friend of mine, who had a male friend (this was the sixties after all) stay at hers theoretically for the weekend, but he didn't leave for a week and she was too polite to tell him to shove off.
Sure, but that's a pretty different situation. Instead of traveling strangers its a friend, instead of a confident dude who will kick someone out, it's a demure shy girl. So I'm not worried at all.
