10 tips to save on your car rental in and around Western Illinois

1. Use filters to find the right car: Refine your search by specifying vehicle type and features. Whether you’re looking for an SUV for additional space, a convertible for summer fun, or an economy car for cost-effectiveness, utilize the filters on Expedia to discover the perfect option for your trip.
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 travel dates. Booking in advance often leads to lower rates and better availability, particularly during peak seasons.
3. Consider a smaller car for savings: Smaller vehicles are typically less expensive to rent and easier to maneuver and 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 vehicle categories—such as SUVs or luxury models—might be unavailable. 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 charges. This is generally the best option. Others may provide full-to-empty or prepaid fueling choices, which are acceptable as well; just ensure you return the car with an empty tank in those cases.
6. Save on city and airport pickups: There is often an extra fee for picking up your rental car at the airport, but it may be worth it for the added convenience.
7. Know your payment options: Many car rental companies only accept credit cards for transactions.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provides peace of mind should anything unforeseen occur during your travels. Adding car rental insurance is simple when you book through Expedia.
9. Consider unlimited mileage: If you're planning long road trips, look for rental options 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 car.
