@Richard-And-Elizabeth1 Are you sure that one night bookings are worth the hassle? You can always raise your minimum stay, or limit your room to only solo guests, if you're bothered that mutually consenting adults are having sex in their private room.
But even then, it still helps to become a bit of a stain removal expert. Tip: the key to getting oil-based lube stains out of sheets is to rub some dishwashing liquid such as Dawn into the spot and leave it for a few minutes before washing.
