What does hotel min nights (aka MLOS, or minimum length of stay) mean?
A minimum length of stay restriction only shows the stay as bookable if the stay is equal to or greater than the minimum nights setting.
If the 10th has an MLOS restriction of 3 nights, and the guest searches for the 10th through the 12th, a 2 night stay, the stay will not show as available, as the minimum night restriction of 3 has not been met.
If the guest searches for the 10th through the 13th, a 3 night stay, the stay will appear as bookable.
This is also known as “minimum nights on arrival” as the restriction is only in effect when the stay arrival starts on the date with the minimum stay restriction.
