10 tips to save on your St. Charles car hire

1. Use filters to find the right car: Refine your search by selecting vehicle types and features. Whether you're looking for an SUV for extra space, a convertible for summer enjoyment, or an economy car to save money, use the filters on Expedia to discover the perfect match for your journey.
2. Book in advance to help lower costs: Rental rates can vary based on demand, so it's advisable to reserve your vehicle well ahead of your travel dates. By booking in advance, you’re more likely to secure lower prices and better availability, particularly during peak travel seasons.
3. Consider a smaller car for savings: Smaller vehicles are typically less expensive to rent and easier to park in crowded locations. Mid-size rentals strike a good balance between affordability, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 years may encounter higher deposits or daily fees, and certain types of vehicles—like SUVs or luxury models—might not be available. This may also apply to renters over the age of 70. 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 charges. This option is usually the most economical. Other policies may allow full-to-empty or prepaid fueling options, which can also be convenient. Just remember to return the car empty if you choose this option.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the added convenience may make it worthwhile.
7. Know your payment options: Many 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 extra peace of mind if something unforeseen occurs during your trip. You can easily add car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you’re planning long road trips, search for 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 vehicle.
