10 tips to save on your car rental around Mauna Kea Observatory

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 those sunny days, or an economy car for budget-friendly travel, utilize the filters on Expedia to discover the best options 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're more likely to lock in lower rates and enjoy a wider selection, especially during peak travel seasons.
3. Consider a smaller car for savings: Compact vehicles are typically less expensive to rent and easier to maneuver in crowded areas. Mid-size rentals offer a great balance of affordability, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and certain types of vehicles—such as SUVs or luxury models—might not be available. This could also apply to renters over 70 years old. Always verify the age requirements before completing your booking.
5. Check fuel policies: Some rentals operate on a full-to-full fuel policy, meaning you need to return the vehicle with a full tank to avoid extra charges. This is typically the most advantageous option. Others may offer full-to-empty or prepaid fueling alternatives, which can also be acceptable—just ensure you return the car with an empty tank in that 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 primarily 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 happens during your trip. It's easy to include car rental insurance when making a reservation with Expedia.
9. Consider unlimited mileage: If you’re planning long road trips, look for rentals that offer unlimited mileage to prevent incurring additional charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a vehicle.
