10 tips to save on your car rental in New Castle County

1. Use filters to find the right car: Refine your search by vehicle type and specific features. Whether you're looking for an SUV for additional space, a convertible for summer fun, or an economy car for budget-friendly options, utilize the filters on Expedia to help you discover the perfect vehicle for your journey.
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 early, you stand a better chance of securing lower rates and greater availability, particularly during peak seasons.
3. Consider a smaller car for savings: Compact cars are typically more affordable to rent and easier to maneuver and park in crowded areas. Mid-size rentals strike a good balance between cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily surcharges, and certain vehicle types—such as SUVs or premium models—might not be available. This can also apply to renters over 70 years old. Always verify the age requirements prior to booking.
5. Check fuel policies: Some rental agreements require a full-to-full fuel policy, meaning you must return the car with a full tank to avoid extra fees. This option is often the most economical. Other policies may include full-to-empty or prepaid fueling options, which are also valid. Just ensure you return the car with an empty tank in that case.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but it may be worth it for the added convenience.
7. Know your payment options: Many car rental companies primarily accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provides peace of mind in case of unforeseen events during your trip. Adding car rental insurance is straightforward when booking through Expedia.
9. Consider unlimited mileage: If you're planning on taking long road trips, seek out rentals that offer unlimited mileage to prevent additional charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
