10 tips to save on your O'Fallon car hire

1. Use filters to find the right car: Refine your search by vehicle type and specific features. Whether you need an SUV for added space, a convertible for summer enjoyment, or an economy car for cost-effectiveness, utilize the filters on Expedia to discover the ideal option for your journey.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it's advisable to secure your car well ahead of your trip. By booking early, you're more likely to obtain lower rates and better availability, particularly during peak travel seasons.
3. Consider a smaller car for savings: Generally, smaller cars are more affordable to rent and easier to park in crowded areas. Mid-size rentals strike a good balance between price, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily surcharges, and certain vehicle types—such as SUVs or premium models—might not be available. Renters over 70 years old may also face similar restrictions. 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 option is usually the most advantageous. Other policies may include full-to-empty or prepaid fueling options, which can also be acceptable; just ensure you return the car empty in those cases.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but this extra cost might be worthwhile for the convenience it offers.
7. Know your payment options: Many car rental companies primarily accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected costs and provides peace of mind in case of unforeseen events during your trip. Adding car rental insurance when booking through Expedia is simple.
9. Consider unlimited mileage: If you're planning long road trips, seek rentals that offer unlimited mileage to prevent extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
