A minimum advance reservation time establishes the minimum amount of time before check-in that a guest can book a room or unit.
For exemple, if you want guests to book at least two days in advance of check-in, the minimum advance reservation time is 2 days.
Thus, if today a client checks for available accommodations tomorrow, your accommodation will not be displayed by filters and cannot be booked.
The number of days included in the field corresponding to the "Minimum Advance Reservation" function is calculated taking into account the check-in time.
