1. Go to Settings -> Availability -> Stay days & length and click “New adjustment”.
2. Indicate the date range and weekdays when this setting should apply.
3. Unless you specify a particular room type, this setting will apply to all room types.

5. Under “Choose here”, select to accept only full week bookings.

When you’ve done the above, continue by following these steps:

1. Go to Settings -> Availability -> Stay restrictions and click “New restriction”.
2. Enter a name for the restriction and indicate the date range when the restriction should apply.
3. Unless you specify a room type, this setting will apply to all room types.
4. Under “Blocked days”, choose the weekdays when check-in should be closed, for example, all days except Saturdays.
5. Check the box “Check-in not allowed”.
