Is this even new? Once (~10 years ago) I was staying in Vegas (MGM Grand) with my gf. She was working for a couple of days from the room while I was downstairs gambling so we had the dnd sign out, so she could work without stopping for housekeeping. After the 2nd day security came by to make sure that "everything was ok". I was not there at the time but it did not sound like a big imposition.
