10 tips to save on your car rental in and around Port Costa

1. Use filters to find the right car: Refine your search by selecting the vehicle type and features that suit your needs. Whether you’re looking for an SUV for extra room, a convertible for summer drives, or an economy car for budget-friendly options, utilize the filters on Expedia to discover the best fit for your journey.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it’s advisable to secure your car well ahead of your trip. By booking early, you are more likely to obtain lower rates and better availability, especially during peak travel seasons.
3. Consider a smaller car for savings: Generally, smaller cars are less expensive to rent and easier to park in crowded areas. Mid-size rentals offer a good compromise 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 luxury models—might not be available. This can also apply to renters over 70. 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 need to return the car with a full tank to avoid additional charges. This is usually the most advantageous option. Other policies might include full-to-empty or prepaid fueling options, which are acceptable as well—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 convenience it offers 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 provides peace of mind in case something unforeseen occurs during your trip. It’s easy to add car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you plan to take long road trips, search for rentals that offer unlimited mileage to prevent additional charges.
10. Bring your driver's license and ID: A valid driver’s license is mandatory to rent a car.
