What happens if I bring my rental car back late?
There is generally a 29 minute grace period for daily rentals. ... If you return the vehicle 2 ½ hours or more from the time it was rented on a subsequent day, you will be charged for an additional day of rental. Please Note: A vehicle that is returned after hours will not be checked in until the next business day.
