10 tips to save on your car rental in and around Marathon

1. Use filters to find the right car: Refine your search by vehicle type and features. Whether you require an SUV for additional space, 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 rates can vary based on demand, so it's advisable to secure your car well ahead of your trip. Booking early often allows you to lock in lower prices and ensures better availability, particularly during peak travel seasons.
3. Consider a smaller car for savings: Compact cars are typically more affordable to rent and easier to park in crowded areas. Mid-size vehicles 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 categories—such as SUVs or luxury models—might not be available. This can also apply to renters over 70. Always verify the age requirements prior to booking.
5. Check fuel policies: Some rentals operate under a full-to-full fuel policy, requiring you to return the car with a full tank to avoid extra fees. This is generally the best choice. Other options may include full-to-empty or prepaid fueling, which is acceptable as well; just remember to return the vehicle empty in that case.
6. Save on city and airport pickups: Picking up your rental car at the airport often incurs an additional surcharge, but the convenience may justify the extra cost.
7. Know your payment options: Most car rental companies only accept credit cards for payment.
8. Understand your insurance coverage: Rental car insurance can help you avoid unexpected expenses and provides peace of mind in case of unforeseen circumstances during your trip. Adding car rental insurance when booking through Expedia is straightforward.
9. Consider unlimited mileage: If you're planning long road trips, look for rentals that offer unlimited mileage to prevent additional charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
