''''Unit Allocation''': "One per booking" will allocate one room for each booking. This is the normal setting for a hotel room etc. "One Per Guest" will allocate one unit for each person in the booking. This is typical for a hostel selling beds or for activity or event tickets which are allocated per person.
'''Room Availability:''' This setting is useful if for example this is a suite that is composed of this and an adjoining room or you are offering a more exclusive occupancy (at higher price?) when another room is unoccupied. A booking for this room will block the other room for the duration of the booking.
'''Requires Availability in:''' Defines the other second room which has to be available.
'''Combination Logic:''' And logic means both rooms must be available
Or logic means at least one of the rooms must be available.
'''Assign Bookings'''
'''Assign Bookings to:''' By default web bookings for a room will be assigned to the selected room. It can be manually assigned to a different room. If assigned to a different room the booking will be assigned there without further checking availability in the assigned room.
'''Assign a Copy Booking to:''' A copy of the booking can be placed in another room. This can be used to control availability in dependant and linked rooms.
