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

1. Use filters to find the right car: Refine your search by vehicle type and features. Whether you're looking for an SUV for added space, a convertible for summer fun, or an economical car for budget-friendly travel, utilize the filters on Expedia to discover the best options for your trip.
2. Book in advance to help lower costs: Rental rates vary depending on demand, so it's advisable to secure your car well ahead of your travel dates. Booking early typically allows you to lock in lower prices and ensures better availability, especially during peak seasons.
3. Consider a smaller car for savings: Smaller vehicles are usually more affordable to rent and easier to maneuver in crowded areas. Mid-size cars offer a nice balance of cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily surcharges, and certain vehicle categories—such as SUVs or luxury models—might not be available. This can also apply to renters over the age of 70. Always verify the age criteria before finalizing your booking.
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 generally the most favorable option. Other policies may include full-to-empty or prepaid fueling options, which are also acceptable. Just ensure you return the car with an empty tank in that case.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs an additional surcharge, but the convenience may justify the cost.
7. Know your payment options: Many car rental companies accept only credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provides peace of mind in case of unforeseen incidents during your trip. Adding car rental insurance is a simple process when booking through Expedia.
9. Consider unlimited mileage: If you plan on taking long road trips, seek out rentals that offer unlimited mileage to prevent extra fees.
10. Bring your driver's license and ID: A valid driver's license is required to rent a vehicle.
