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

  1. Use filters to find the right car: Refine your search by selecting the vehicle type and features that best suit your needs. Whether you're looking for an SUV for added space, a convertible for summer enjoyment, or an economy car for budget-friendly travel, utilize the filters on Expedia to discover the ideal option for your journey.
  2. Book in advance to help lower costs: Rental rates can vary based on demand, so it’s advisable to secure your car well ahead of your travel dates. By booking early, you’re more likely to access lower prices and a wider selection, especially during busy seasons.
  3. Consider a smaller car for savings: Compact cars are typically more affordable to rent and easier to maneuver in crowded areas. Mid-size vehicles strike a good balance 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 categories—such as SUVs or premium models—might not be available. This could also apply to renters over the age of 70. Be sure to 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 option is often the most economical. Other policies may offer full-to-empty or prepaid fueling options, which are also acceptable. Just remember to return the vehicle with an empty tank in those cases.
  6. Save on city and airport pickups: Picking up your rental car at the airport 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 protect you from unexpected expenses and provide peace of mind during your trip. Adding car rental insurance when booking through Expedia is a straightforward process.
  9. Consider unlimited mileage: If you're planning extensive road trips, look for rental options that offer unlimited mileage to avoid incurring additional charges.
  10. Bring your driver's license and ID: A valid driver's license is a necessary requirement for renting a car.
