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

1. Use filters to find the right car: Refine your search by selecting vehicle type and specific features. Whether you're looking for an SUV for extra space, a convertible for summer drives, or an economy car for budget-friendly options, utilizing filters on Expedia can 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 wise to secure your car well ahead of your trip. By booking early, you’re more likely to find lower rates and have a greater selection, particularly during peak travel seasons.
3. Consider a smaller car for savings: Compact cars are typically more affordable to rent and easier to maneuver 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 fees, and certain vehicle categories—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 rental agreements require a full-to-full fuel policy, which means you must return the car with a full tank to avoid additional charges. This is generally the most favorable option. Others may offer full-to-empty or prepaid fueling options, which are acceptable as well. Just ensure you return the car empty in that scenario.
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: 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 in case something unforeseen occurs during your trip. Adding car rental insurance when booking through Expedia is a straightforward process.
9. Consider unlimited mileage: If you plan to take long road trips, look for rental options that offer unlimited mileage to prevent incurring extra charges.
10. Bring your driver's license and ID: A valid driver's license is required to rent a vehicle.
