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

1. Use filters to find the right car: Refine your search by selecting vehicle type and desired features. Whether you're looking for an SUV for added space, a convertible for summer outings, or an economy car for budget-friendly travel, the filters on Expedia can assist you in finding the perfect match for your trip.
2. Book in advance to help lower costs: Rental rates can vary based on demand, so it's advisable to reserve your car well ahead of your trip. By booking early, you are likely to secure lower rates and enjoy better availability, particularly during peak seasons.
3. Consider a smaller car for savings: Smaller vehicles are typically more affordable to rent and easier to maneuver in busy areas. Mid-size rentals strike a good balance between cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under the age of 30 may encounter higher deposits or daily surcharges, and certain vehicle categories—like SUVs or premium models—might not be available. Renters over the age of 70 could also face similar restrictions. Always verify the age requirements before making a reservation.
5. Check fuel policies: Some rental companies require a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional fees. This is often the most cost-effective option. Other companies may offer full-to-empty or prepaid fueling options, which can also be convenient. Just ensure you return the vehicle empty in that case.
6. Save on city and airport pickups: Picking up your rental car at the airport often incurs a surcharge, but the convenience may be worth the extra cost.
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. Adding car rental insurance while booking with 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 necessary to rent a vehicle.
