10 tips to save on your car rental around Six Flags St. Louis

1. Use filters to find the right car: Refine your search by selecting vehicle type and desired features. Whether you're looking for an SUV for extra room, a convertible for summer fun, or an economy car for budget-friendly travel, utilize Expedia's filters to discover the perfect option for your journey.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it's advisable to reserve your car well ahead of your travel dates. Booking in advance often secures lower rates and improves availability, particularly during peak seasons.
3. Consider a smaller car for savings: Smaller vehicles typically have lower rental costs and are easier to maneuver and park in crowded areas. Mid-size cars offer a solid balance between price, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and certain vehicle categories—such as SUVs or premium models—might not be available. This could also apply to renters over the age of 70. Always verify the age requirements prior to booking.
5. Check fuel policies: Some rental agreements require a full-to-full fuel policy, meaning you must return the vehicle with a full tank to avoid additional fees. This option is generally the most cost-effective. Other policies may include full-to-empty or prepaid fueling, which is acceptable as well—just ensure you return the car with an empty tank in this 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: Most car rental companies exclusively accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can protect you from unforeseen expenses and provide peace of mind in case of unexpected incidents during your trip. It's easy to add insurance when booking through Expedia.
9. Consider unlimited mileage: If you plan to take long road trips, seek rentals that offer unlimited mileage to avoid incurring extra charges.
10. Bring your driver's license and ID: A valid driver's license is essential for renting a car.
