Abstract: Systems and methods are disclosed herein for creating and managing rental vehicle reservations. According to one embodiment, a system is disclosed for creating and managing a rental vehicle reservation, the system comprising: (a) a user computer, and (b) a reservation computer system that is in communication with the user computer via a network, and wherein the reservation computer system is configured to accept input from a user of the user computer over the network to create a pended rental vehicle reservation for storage and processing by the reservation computer system. The inventors herein believe that the ability of a reservation computer system to maintain such a pended status for rental vehicle reservations is particularly useful in connection with processing vouchers for replacement rental vehicles.
