10 tips to save on your car rental in and around Southwest Harbor

1. Use filters to find the right car: Refine your search by selecting vehicle type and features. Whether you're looking for an SUV with extra space, a convertible for summer drives, or an economy car for budget-friendly travel, utilize the filters on Expedia to discover the perfect match for your journey.
2. Book in advance to help lower costs: Rental rates can vary based on demand, so it's wise to secure your vehicle well ahead of your trip. By booking early, you’re likely to lock in lower rates and enjoy a wider selection, especially during peak travel seasons.
3. Consider a smaller car for savings: Generally, smaller cars are more affordable 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 fees, and certain vehicle types—such as SUVs or luxury models—might not be available. This policy can also apply to renters over 70 years old. Always verify the age requirements prior to booking.
5. Check fuel policies: Some rental agreements require a full-to-full fuel policy, meaning you need to return the car with a full tank to avoid additional charges. This is usually the most economical choice. Other options may include full-to-empty or prepaid fueling, which can also be acceptable; just remember to return the vehicle empty in that case.
6. Save on city and airport pickups: Picking up your rental car at an airport often incurs a surcharge, but the added convenience may be worth the extra cost.
7. Know your payment options: Most car rental companies exclusively accept credit cards for payment.
8. Understand your insurance coverage: Rental car insurance can help you avoid unexpected expenses and provide peace of mind if something goes wrong during your trip. Adding car rental insurance when booking through Expedia is a straightforward process.
9. Consider unlimited mileage: If you plan to embark on long road trips, seek out rentals that offer unlimited mileage to sidestep extra charges.
10. Bring your driver's license and ID: A valid driver's license is mandatory for renting a car.
