Determine your destination. Rental cars are much more expensive in some locations in the country versus others. If you have a choice in locations for your trip, you may be able to save a few hundred dollars by traveling to a location that offers cheaper cars. For example, Orlando, Florida is one of the more expensive rental locations because it's one of the highest-volume car rental cities. Traveling to Tampa instead may result in a cheaper rental car.
