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 vehicle type and specific features. Whether you're looking for an SUV for extra space, a convertible for summer enjoyment, or an economy car for budget-friendliness, utilize the filters on Expedia to find the perfect match for your trip.
  2. Book in advance to help lower costs: Rental rates can vary based on demand, so it's wise to reserve your car well ahead of your trip. By booking in advance, you're likely to secure more competitive rates and enjoy better availability, particularly during peak seasons.
  3. Consider a smaller car for savings: Smaller vehicles typically come at a lower rental cost and are easier to park in crowded areas. Mid-size rentals strike a good balance between affordability, comfort, and fuel efficiency.
  4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and certain vehicle types—such as SUVs or premium models—might not be available. This can also apply to renters over 70. 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 additional charges. This is often the most economical choice. Other options may include full-to-empty or prepaid fueling, which can also be convenient; just remember to 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 make it worthwhile.
  7. Know your payment options: Many car rental companies only accept credit cards for payment.
  8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provide peace of mind in case of unforeseen incidents during your trip. Adding car rental insurance is straightforward when booking through Expedia.
  9. Consider unlimited mileage: If you're planning long road trips, seek rentals that offer unlimited mileage to prevent additional charges.
  10. Bring your driver's license and ID: A valid driver's license is necessary for renting a car.
