This reminds me of a stay I had once had at an airport hotel. Got in very late at night and went right to bed. Could not believe how noisy the room was, even for an airport hotel. When I got up in the morning and pulled back the curtains, I saw I had slept right under the airport flight pattern with the window OPEN all night. Never thought to check the window. Once I closed and locked the window, you would not believe how quiet the room got! Shame on me, always check the windows and doors. (and maybe it is just me, but the closet and behind the shower curtain, cause I know that's where the bogey man lives).
