In general, dropping off a rental car at a different location can be more expensive than returning it to the same location where you picked it up. This is because rental car companies often charge a "one-way" fee for the convenience of allowing you to drop off the car at a different location.
The one-way fee can vary depending on the rental car company and the distance between the pick-up and drop-off locations. It can range from a flat fee to a per-mile charge. Additionally, if you drop off the car in a different state or country, you may also be subject to additional fees and taxes.
To avoid these extra charges, you can try to plan your trip so that you return the car to the same location where you picked it up. However, if dropping off the car at a different location is necessary for your trip, be sure to research the fees and factor them into your budget when comparing rental car prices.
