The way I understand the OP is this couple would be staying for one night only.
The chances are zero to none that they’d be doing the nasty in someone else’s bed as a guest. - Solomon
A close relative uses a basement room as an Air B&B for short term stays. They had a couple stay for one night to attend a friend's wedding. After returning from the wedding reception during the night, this couple proceeded to wake-up everyone in the house while performing an extended sex session which included unrestrained moaning and banging against the headboard and against the walls within the shower.
