Most accommodation operators prefer guests who book longer stays.
One-night stays are not very popular due to higher costs for cleaning, changing sheets, towels, check-in, check-out.
Some operators solve this by setting a minimum number of nights for accommodation. You can set this in Trevlix as a "restriction" in the Pricing module.
Other operators solve this by offering price discounts for longer stays.
It would seem logical to solve this with a surcharge for a short stay. Unfortunately, none of the main accommodation catalogs support this function.
All major global accommodation catalogs such as Booking.com solve this problem with a discount for longer stays.
Thus, guests do not have the negative feeling that they are being punished for a short stay, but rather the positive feeling that they are being rewarded for a longer stay.
