not hotel, but i hear the couple upstairs from my flat screwing all the time. They are REALLY loud. Well actually, she is really loud - never hear him. The way she screams, I can only assume he is about 12 inches long and ramming it in her ass. Turns me on SO much to hear them. But then I love watching porn too. I love watching other people have sex, so hearing it but not being able to watch is both a turn on and really frustrating that i can't see!
