Anyone been here recently? Seems weird that DEN National would have no cars.
Just keep your original time. National does not charge a penalty for early pick up in my experience.
Just keep in mind that you will need to return earlier to avoid extra charges (1 day = 24hr block). Example - you pick up at 3pm instead of 8pm, return at 3pm to avoid charges.
