The rental program is entirely voluntary. It allows the owner of a unit to make it available for rental to the public through the hotel's management company. If an owner decides to participate in the program, he/she enters into a unit rental agreement with the hotel's manager that provides for marketing and rental of the room as a hotel room by the manager in return for a rent to be paid to the room owner. In order to maintain control over the hotel's room inventory, the unit rental agreement provides for a minimum number of days that the owner must make the room available to the manager for rental to the public.
