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 vehicle type and features. Whether you’re looking for an SUV for extra room, a convertible for summer fun, or an economical 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 rates vary with demand, so it’s wise to secure your car well ahead of your trip. By booking early, you’re more likely to lock in lower prices and enjoy greater availability, particularly during peak travel seasons.
3. Consider a smaller car for savings: Compact cars are typically 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 specific vehicle types—such as SUVs or luxury models—might not be accessible. This could also apply to renters over 70 years old. Always verify the age stipulations before making a reservation.
5. Check fuel policies: Some rentals operate under a full-to-full fuel policy, which requires you to return the vehicle with a full tank to avoid additional charges. This is usually the most advantageous option. Others might offer full-to-empty or prepaid fueling alternatives, 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 convenience may make it worthwhile.
7. Know your payment options: Many car rental companies primarily accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provide peace of mind if anything unforeseen occurs during your trip. It’s easy to add car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you’re planning extensive road trips, seek 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.
