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

1. Use filters to find the right car: Refine your search based on vehicle type and features. Whether you require an SUV for extra space, a convertible for summer fun, or an economy car for budget-friendly travel, utilize filters on Expedia to discover the perfect vehicle for your journey.
2. Book in advance to help lower costs: Rental prices can vary with demand, so it's advisable to secure your car well ahead of your trip. By booking early, you are more likely to lock in lower rates and enjoy a wider selection, especially 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 vehicles offer a good compromise between price, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and certain vehicle types—such as SUVs or premium models—might not be available. 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 require a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional charges. This is usually the most economical option. Others may provide full-to-empty or prepaid fueling choices, which are acceptable as well; just ensure you return the car empty in that scenario.
6. Save on city and airport pickups: Picking up your rental at airports often incurs a surcharge, but the added convenience may make it worthwhile.
7. Know your payment options: Most car rental companies exclusively 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 when booking through Expedia is straightforward.
9. Consider unlimited mileage: If you plan to embark on 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.
