10 tips to save on your car rental in and around Frontenac

1. Use filters to find the right car: Refine your search by vehicle type and features. Whether you need an SUV for extra space, a convertible for summer fun, or an economy car for budget-friendly travel, utilize filters on Expedia to discover the best option for your journey.
2. Book in advance to help lower costs: Rental prices vary based on demand, so it's advisable to reserve your car well ahead of your trip. Booking early often secures lower rates and ensures better availability, especially during peak seasons.
3. Consider a smaller car for savings: Smaller vehicles typically come at a lower rental cost and are easier to 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 types—such as SUVs or premium models—might not be available. This can also apply to renters over 70. Always verify the age restrictions before making a reservation.
5. Check fuel policies: Some rentals operate under a full-to-full fuel policy, requiring you to return the car with a full tank to avoid additional charges. This is generally the best choice. Other options may include full-to-empty or prepaid fueling, which can also be convenient. Just remember to return the car empty in that case.
6. Save on city and airport pickups: Renting a car at the airport often incurs a surcharge, but this added convenience may be worth the cost.
7. Know your payment options: Many car rental companies accept only credit cards for payments.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and offers peace of mind in case of unforeseen events during your trip. Adding car rental insurance while booking through Expedia is a straightforward process.
9. Consider unlimited mileage: If you plan on taking long road trips, look for rental options that include 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.
