Pick the closest lowest price Hilton to your house, book a room, drive by, check in, go to the room, leave the key there and go home.
That will count as a stay, you can mess up the bed you think it will help.
I've got two hiltons chain hotels within two miles of the house, if I ever needed one last stay that's what I would do.
If they ask, though they won't, tell them you are getting your floors done, it's the wife's night with the girls, whatever.
