If a member of the Dollar Rent A Car Express Renter Rewards program does not rent a vehicle for an extended period, their account may remain active, but they may not earn additional rewards or points during that time. The specifics can vary based on the current policies of Dollar Rent A Car. It is possible that inactive accounts after a certain period could face expiration, but this typically depends on the terms set forth by the program. It is advisable for members to periodically check their account status to stay informed about any updates or changes to their rewards status. Additionally, members can regularly review the Dollar Rent A Car website to obtain the most accurate information regarding account activity and rewards. This can help ensure that they remain eligible for any upcoming promotions or benefits.
