Whether you’re looking for an SUV for added space, a convertible for summer enjoyment, or an economy car to save money, utilize the filters on Expedia to discover the ideal match for your trip.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it’s advisable to reserve your car well ahead of your trip. By booking in advance, you’re likely to secure lower rates and have better availability, particularly during peak travel seasons.
3. Consider a smaller car for savings: Smaller vehicles are typically more affordable to rent and easier to maneuver in crowded areas. Mid-size rentals offer a balanced option in terms of cost, comfort, and fuel efficiency.

5. Check fuel policies: Some rentals operate on a full-to-full fuel policy, which means you must return the car with a full tank to avoid additional charges. This is often the most advantageous option. Other policies may include full-to-empty or prepaid fueling options, which are acceptable as well; just ensure to return the car empty in those cases.
6. Save on city and airport pickups: While you may incur a surcharge for picking up your rental car at airports, the added convenience may justify the extra cost.
