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

1. Use filters to find the right car: Refine your search by vehicle type and features. Whether you need an SUV for extra room, a convertible for summer enjoyment, or an economy car for budget-friendliness, utilize the filters on Expedia to help you discover the perfect match 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 car well ahead of your trip. By booking in advance, you are more likely to secure lower rates and better availability, particularly during peak seasons.
3. Consider a smaller car for savings: Smaller vehicles are typically less expensive 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 surcharges, and certain vehicle types—such as SUVs or premium models—might not be available. This can also apply to renters over the age of 70. Always verify the age requirements before making a reservation.
5. Check fuel policies: Some rentals operate under 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 advantageous option. Others may provide full-to-empty or prepaid fueling alternatives, which are acceptable as well. Just remember to return the car empty in this 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 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. It's easy to add car rental insurance when you book with Expedia.
9. Consider unlimited mileage: If you plan on taking long road trips, search for rentals that offer unlimited mileage to prevent incurring extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
