10 tips to save on your car rental in and around Old Monroe

1. Use filters to find the right car: Streamline your search by selecting vehicle types and features. Whether you’re looking for an SUV for extra space, a convertible for summer fun, or an economy car for budget-friendly travel, 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 in advance of your trip. By booking early, you’re more likely to access lower rates and enjoy better availability, especially during peak travel seasons.
3. Consider a smaller car for savings: Smaller vehicles are typically more affordable to rent and easier to maneuver in crowded areas. Mid-size rentals offer a balanced combination of cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 years old may encounter higher deposits or daily fees, and certain vehicle categories—such as SUVs or premium models—might not be available. This can also apply to renters over 70 years of age. Always verify the age requirements prior to making a reservation.
5. Check fuel policies: Some rental agreements require a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional charges. This is often the most advantageous option. Other agreements may offer full-to-empty or prepaid fueling options, which can also be acceptable. Just remember to return the car empty 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 justify the cost.
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 if something unforeseen occurs during your trip. Adding car rental insurance is simple when booking through Expedia.
9. Consider unlimited mileage: If you’re planning long road trips, seek out rentals 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 car.
