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

1. Use filters to find the right car: Refine your search by selecting the vehicle type and desired features. Whether you're looking for an SUV for extra room, a convertible for summer drives, or an economy car for budget-friendly travel, utilize the filters on Expedia to identify 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 make your reservation well ahead of your trip. By booking early, you're more likely to secure lower rates and better availability, especially during peak travel seasons.
3. Consider a smaller car for savings: Compact cars are typically more affordable to rent and easier to park in crowded areas. Mid-size vehicles offer a great compromise between cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under the age of 30 may encounter higher deposits or daily fees, and certain vehicle types—such as SUVs or luxury models—might not be available. This can also apply to renters over the age of 70. 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 vehicle with a full tank to avoid additional charges. This is often the preferred option. Other policies may include full-to-empty or prepaid fueling options, which are acceptable as well. Just be sure to return the car empty in those cases.
6. Save on city and airport pickups: A surcharge is often applied for picking up your rental car at airports, but it may be worth the extra cost for the convenience it provides.
7. Know your payment options: Many car rental companies only accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provides peace of mind in case something unforeseen occurs during your trip. It's simple to add rental car insurance when booking through Expedia.
9. Consider unlimited mileage: If you're planning long road trips, seek out rental options 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.
