10 tips to save on your car rental in and around St. Charles

  1. Use filters to find the right car: Refine your search by selecting vehicle type and features. Whether you’re looking for an SUV for extra space, a convertible for summer fun, or an economical car for budget savings, utilize the filters on Expedia to identify the best options for your journey.
  2. Book in advance to help lower costs: Rental prices vary based on demand, so it's advisable to reserve your vehicle well ahead of your trip. By booking early, you’re likely to secure lower rates and enjoy a wider selection, particularly during peak 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 rentals offer a nice balance of cost, comfort, and fuel efficiency.
  4. Age guidelines: Drivers under 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 restrictions prior to booking.
  5. Check fuel policies: Some rentals operate on a full-to-full fuel policy, meaning you must return the vehicle with a full tank to avoid additional charges. This is generally the most favorable option. Other policies may include full-to-empty or prepaid fueling options, which are acceptable as well; just ensure you return the car empty in that scenario.
  6. Save on city and airport pickups: Picking up your rental car at the airport often incurs a surcharge, but it may be worthwhile for the added convenience.
  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 in case something unforeseen occurs during your trip. Adding car rental insurance when booking through Expedia is straightforward.
  9. Consider unlimited mileage: If you're planning on taking long road trips, seek out 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 car.
