You can set your turn days directly in Art.  Turn days are specific days for check-in or check-out.  This feature is currently available for Track, Guesty and Escapia users only.  

To set turn days, or designated check-in or check-out days, select dates directly on the tape chart.  

In the flyout window, scroll past the override section to the turn day section.  

Click set days and disable any days you don't want to allow for a check-in.  Do the same for the check out days.  Then hit save.

Art will then display with icons small keys with a dash through it.  This means check-in and check-out are not allowed.  

You can also see it when you hover over the day.
