I'd like to rent a car in the US to go from city A to city B (~5-hour drive), and then back from B to A within 1 week. I have no use for the car during the week, but renting one-way is significantly more expensive than for a round trip.
What I would like to do is to rent the car at city A, go to B, return it, then one week later pick it up again (or any other car), and go back to A, while being charged as in a round trip (paying for two days' rent, not one week's rent).
Is this possible? Does anyone know any company that offers such a service?
