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

  1. Use filters to find the right car: Streamline your search by specifying vehicle type and 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 prices can vary with demand, so it’s wise to secure your car well ahead of your trip. By booking early, you’re more likely to benefit from lower rates and improved availability, especially during peak travel seasons.
  3. Consider a smaller car for savings: Compact cars typically come at a lower rental cost and are easier to maneuver in crowded areas. Mid-size vehicles offer a nice balance between affordability, 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 70 may also face similar restrictions. Always verify the age requirements before finalizing your booking.
  5. Check fuel policies: Some rental companies require a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional fees. This option is usually the most economical. Others may provide full-to-empty or prepaid fueling options, which can work too, as long as you return the vehicle with an empty tank in that case.
  6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the convenience may justify the extra cost.
  7. Know your payment options: Most car rental companies primarily 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 of unforeseen events during your trip. It’s simple to add car rental insurance when booking through Expedia.
  9. Consider unlimited mileage: If you’re planning long road trips, seek rentals that offer unlimited mileage to prevent additional charges.
  10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
