@Jane3220 Despite being in a location that gets a lot of 1-2 night visitors, I always found that there were enough 3 night bookings to keep my occupancy rates where I liked them. Having a longer minimum stay paid off in terms of less changeover work, less wear and tear on linens, and more relaxed guests.
It is always an option to selectively offer a lower minimum stay at a higher nightly rate for specific gaps in your calendar you'd like to fill, but defaulting to a higher minimum should get you better bang for your buck on cleaning while also helping discourage illicit parties.
