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

1. Use filters to find the right car: Refine your search by vehicle type and features. Whether you're looking for 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 can vary based on demand, so it's advisable to reserve your vehicle well ahead of your trip. By booking early, you are more likely to secure lower rates and enjoy better availability, particularly during peak travel seasons.
3. Consider a smaller car for savings: Smaller vehicles are typically more affordable to rent and easier to park in crowded areas. Mid-size rentals offer a good compromise between cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily surcharges, and certain vehicle types—such as SUVs or premium models—might not be available. This can also apply to renters over 70 years old. Always 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 fees. This is generally the most favorable option. Others may offer full-to-empty or prepaid fueling options, which can also be convenient. Just remember to return the car empty in that scenario.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the added convenience may be worth the extra cost.
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 if anything unforeseen occurs during your trip. It's easy to add car rental insurance when booking with Expedia.
9. Consider unlimited mileage: If you're planning long road trips, look for rental options that offer unlimited mileage to avoid incurring extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
