Seoul, Korea, 1969: the room wasn't bad, the bedding was clean, the pillow was stuffed with rice husks (very, very hard!). Have you ever used one of those floor-mounted, urinal-on-its-back, squat toilets? Move away from it when you flush. Move away QUICKLY.

Ketchikan, Alaska, 1982 or thereabouts: I don't remember the name of the hotel, but the guy in the next room spent the night shouting at some friend two floors below on the sidewalk to get a case of beer and he'd drop a rope and hoist it up. I have excellent reason to believe both were inebriated.
