10 tips to save on your car rental around St. Louis Union Station

1. Use filters to find the right car: Refine your search by selecting vehicle types and specific features. Whether you require an SUV for additional space, a convertible for summer drives, or an economy car to save money, utilize the filters on Expedia to discover the best option for your journey.
2. Book in advance to help lower costs: Rental rates can vary based on demand, so it's advisable to secure your car well ahead of your travel dates. By booking early, you're more likely to snag lower rates and enjoy better availability, particularly during peak seasons.
3. Consider a smaller car for savings: Smaller vehicles are typically more affordable to rent and easier to park 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 some vehicle types—such as SUVs or premium models—might not be available. This can also apply to renters over 70 years old. Always verify 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 extra fees. This is generally the most advantageous option. Others may provide full-to-empty or prepaid fueling options as well, which can be acceptable too—just ensure you return the car empty in that case.
6. Save on city and airport pickups: There is often an additional fee for picking up your rental car at airports, but the convenience may justify the extra cost.
7. Know your payment options: Many car rental companies exclusively accept credit cards for payments.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and offers peace of mind in case something unforeseen occurs during your trip. Adding car rental insurance while booking with Expedia is a straightforward process.
9. Consider unlimited mileage: If you plan on taking long road trips, search for 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.
