10 tips to save on your car rental in and around New Castle

1. Use filters to find the right car: Refine your search by selecting vehicle types and features. Whether you're looking for an SUV for extra space, a convertible for sunny days, or an economy car for budget-friendly travel, utilize the filters on Expedia to identify the best option for your journey.
2. Book in advance to help lower costs: Rental prices vary based on demand, so it's advisable to reserve your vehicle well ahead of your trip. By booking early, you're more likely to secure lower rates and enjoy a wider selection, especially 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 strike a good balance between price, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and some 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 before making a reservation.
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 usually the most cost-effective option. Other policies might include full-to-empty or prepaid fueling options, which are acceptable as well; just ensure you return the car empty in that case.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the added convenience may justify the extra cost.
7. Know your payment options: Many car rental companies only accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can protect you from unexpected expenses and provide peace of mind if something unforeseen occurs during your trip. It's simple to add car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you plan to embark on long road trips, seek rentals that offer unlimited mileage to avoid incurring extra costs.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
