10 tips to save on your car rental in and around San Sebastian

1. Use filters to find the right car: Refine your search by vehicle type and features. Whether you need an SUV for extra space, a convertible for summer drives, 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 wise to reserve your car well ahead of your trip. By booking early, you’re 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 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 fees, and some vehicle types—such as SUVs or luxury models—might not be available. This may also apply to renters over 70. Always verify the age requirements before making a reservation.
5. Check fuel policies: Some rentals implement a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional charges. This is typically the best choice. Other options may include full-to-empty or prepaid fueling, which can also be acceptable. Just ensure you return the car empty in those cases.
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 primarily accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provide peace of mind if something goes awry during your trip. It’s easy to add car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you're planning on taking long road trips, seek rentals that offer unlimited mileage to prevent additional costs.
10. Bring your driver's license and ID: A valid driver's license is required to rent a car.
