Setting minimum stay restriction

The minimum stay button in Prices menu helps you to set restrictions for Master prices and for any other rate plans of yours.
Once you click on the Show tools and then on the Set restrictions button, you will find various filters in the drop down menu:

1 - As a first step, you should select the time period to which would you like to add this restriction. There are several options to select from but if non of them is the one you are looking for, select the last, "Custom" option and select your desired time frame: 

2 - Select the weekdays for which you would like to apply min nights restriction
3 - Select room types to which this restriction will apply.
4 - Enter the min nights
5 - Save your settings. 

Once you saved the restrictions, you can double-check them in the tables of each room type:

You can also modify the restrictions by changing the number in the Minimum stay row in the room tables. As always, finalise the changes by hitting the update button above the table!

Minimum nights restrictions do not apply to the reservations, when you are manually creating them from the PMS/Calendaer view submenu.
