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 features. Whether you're looking for an SUV for additional space, a convertible for summer fun, or an economy car for budget-friendly travel, use the filters on Expedia to discover the best option for your journey.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it’s wise to make your reservation well ahead of your trip. By booking early, you’re more likely to secure lower rates and better availability, particularly during peak seasons.
3. Consider a smaller car for savings: Smaller vehicles typically cost less to rent and are easier to park in crowded areas. Mid-size rentals strike a good balance between affordability, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and certain types of vehicles—such as SUVs or luxury models—might not be available to them. This can also apply to renters over 70 years old. Always verify the age restrictions 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 fees. This is often the most cost-effective choice. Other options may include full-to-empty or prepaid fueling, 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 justify the extra cost.
7. Know your payment options: Most car rental companies only accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provide peace of mind in case of any unforeseen incidents during your trip. It’s easy to add car rental insurance 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 additional charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
