There is no one definitive answer to this question, as the price of one way rentals can vary greatly depending on a number of factors. Some of the main reasons that one way rentals are often more expensive than standard rentals include the distance you are travelling, the type of vehicle you are renting, the rental company you choose, and whether you are booking on a high-demand weekend or holiday. Additionally, many one way rentals require an upfront fee or a deposit in order to make the reservation. Ultimately, there is no simple answer to this question — but if you do your research and shop around, it is possible to get a great deal on one way rentals.
