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 fun, or an economy car to save money, using filters on Expedia can help you find the perfect vehicle for your trip.
2. Book in advance to help lower costs: Rental rates can vary based on demand, so it's wise to reserve your car well ahead of your travel dates. By booking early, you’re more likely to secure better rates and enjoy a wider selection, especially during peak travel seasons.
3. Consider a smaller car for savings: Smaller vehicles are typically more affordable to rent and easier to maneuver and 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 certain types of vehicles—such as SUVs or luxury models—might not be available. Renters over the age of 70 may also face similar restrictions. 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 car with a full tank to avoid additional charges. This is generally the most favorable option. Other policies may offer full-to-empty or prepaid fueling options, which are also acceptable—just ensure you return the car empty in that case.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs an additional surcharge, but the convenience may justify the cost.
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 peace of mind if something unforeseen occurs during your trip. It’s simple to add car rental insurance when you book through Expedia.
9. Consider unlimited mileage: If you’re planning to take long road trips, look for rental options that offer unlimited mileage to prevent incurring additional costs.
10. Bring your driver's license and ID: A valid driver's license is required to rent a vehicle.
