10 tips to save on your car rental in and around Trenton

1. Use filters to find the right car: Refine your search by selecting vehicle type and features. Whether you're in need of an SUV for added space, a convertible to enjoy during the summer, or an economy car for budget-friendly travel, utilize the filters on Expedia to discover the best option 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 vehicle well ahead of your trip. By booking early, you are likely to secure lower rates and have a wider selection, particularly during peak travel seasons.
3. Consider a smaller car for savings: Generally, smaller cars are more affordable to rent and easier to maneuver in crowded areas. Mid-size rentals offer a solid balance of cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and certain vehicle categories—such as SUVs or premium models—might not be available. This can also be relevant for renters over 70. Always verify the age requirements before making a reservation.
5. Check fuel policies: Some rentals operate with a full-to-full fuel policy, which requires you to return the car with a full tank to avoid additional fees. This is typically the most advantageous option. Other policies may offer full-to-empty or prepaid fueling options, which are also acceptable—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 convenience may be worth the extra cost.
7. Know your payment options: Most car rental companies exclusively accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provides peace of mind should something unforeseen occur during your trip. It's easy to add car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you're planning extensive 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 mandatory for renting a car.
