Does National have a grace period for returning a car late?
There is generally a 29 minute grace period for daily rentals. If the vehicle is returned within 2 ½ hours of the time it was rented on a subsequent day additional hourly charges will apply. 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. If returning after hours when a branch is closed, the customer is responsible for the vehicle until the satisfactory check in of the rental vehicle the next business day
