I had a stay at a hampton in Mt. Dora Florida where the offending couple next door trurned out to be a couple of guys. It was an adjoining room so I could pretty well through the door too. Their session was followed by a couple of choice phrases that were a little over the top for me. All unmentionable here.
I didn't take any action, not much I could do really. Just cover up my ears with a pillow! ha!
