By changing the check-in or check-out time of a reservation for a time beyond the standard of your business, system will block the calendar, like the example below:

It works to ensure that you do not receive unwanted bookings from sales channels and have a secure calendar. 

Enabling the configuration

Access [Settings > Reservation Settings > Automatic Blocks]. On the [Would you like to block your calendar on nights before early check-ins or after late check-outs?] field, mark [Yes] and save the changes.

This will happen when the preparation time for the next stay is shorter than your standard check-in and check-out 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.

Setting the policy per listing

To enable a different behavior per listing, just access the listing´s page and click on [Distribution > Reservation Settings > Auto Blocking Settings].

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, will disregard the standard check-in and check-out time policy and will accept reservations on the sales channels even if there is a late check-out on the check-in day of the new reservation or an earlier check-in the next day (if the check-out of the new reservation is the next day as well).

Now that you already know how early check-ins e late check-outs affect you calendar, how about checking out more related subjects?
