10 tips to save on your car rental in and around St. Clair

1. Use filters to find the right car: Refine your search by selecting vehicle types and features. Whether you're looking for an SUV for added space, a convertible for summer drives, or an economy car to save money, utilize the filters on Expedia to discover the best fit for your journey.
2. Book in advance to help lower costs: Rental prices vary based on demand, so it's wise to secure your car well ahead of your trip. By booking in advance, you’re more likely to obtain lower rates and better vehicle 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 crowded areas. Mid-size rentals offer a balanced combination of cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers younger than 30 may encounter higher deposits or daily surcharges, and certain vehicle categories—such as SUVs or luxury models—might not be accessible. This can also apply to renters over the age of 70. Always verify the age requirements before making a reservation.
5. Check fuel policies: Some rental agreements operate on a full-to-full fuel policy, which requires you to return the vehicle with a full tank to avoid additional fees. This is usually the most economical choice. Others might offer full-to-empty or prepaid fueling options, which are acceptable as well—just ensure the car is returned empty in that case.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the convenience may justify the extra cost.
7. Know your payment options: Most 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 if something unforeseen occurs during your trip. Adding car rental insurance while booking with Expedia is a simple process.
9. Consider unlimited mileage: If you plan to take 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.
