You can do this both at the property level and the per night level.
On the main settings tab of the property, there is a field for Only Check In on and a drop down to select the days of the week you wish to allow check-in. It defaults to no restrictions, but if you want to restrict some night, you can check the nights you do want to allow check-in.
There is not currently a field for Only Check Out on. You will need to do this at the per night level.
Per Night level:
Within the pricing tab of the property you can click on a date and the Set Your Daily Rate pop up will appear. You can check boxes to prevent check in or check out on that specific day.
