It works to ensure that you will not receive unwanted reservations from sales channels and have a secure calendar.
Access [Settings > Reservations > Preparation time]. On the [Do you want to block your calendar on nights before check-ins in advance or after late checkouts?] field, select [Yes] and save the changes.
This will happen when the preparation time for the next stay is shorter than your standard check-in and checkout time window, in other words, the best to avoid these cases is to work with a policy that gives some negotiation margin for eventual extensions of stays.
To enable a different behavior per listing, just access the listing's page and click on [Distribution > Reservation settings > Preparation time].
Just click on [Individual], change the configuration and save the changes at the upper right side of the screen:
When clicking on the [Global] button, it will also be possible to see the preview of the configuration that was applied to the system's global model.
On this situation, Stays.net will disregard the standard check-in and checkout time policy and will accept reservations on the sales channels even if there is a late checkout on the check-in day of the new reservation or an earlier check-in the next day (if the checkout of the new reservation is the next day as well).
