Check-out time is at noon, so our reservation calendar may show a calendar day as half green and half red depending on arrival and departure of campers.
The green part of a day can be reserve, the red part of the day is already reserved.
If the first half of a day is red and the second half is green, this means that a reservation will be checking out at noon that day, therefore you would be able to make a reservation to arrive that day.
If the first half of a day is green and the second half is red, this means that a reservation is arriving that day, therefore you can make a reservation up to that day (you can have this as your check-out date). You will not be able to reserve that night.
