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

1. Use filters to find the right car: Refine your search by vehicle type and features. Whether you require an SUV for additional space, a convertible for summer drives, or an economy car for budget-friendly options, utilize the filters on Expedia to discover the best fit for your journey.
2. Book in advance to help lower costs: Rental rates can vary based on demand, so it’s advisable to reserve your car well in advance of your trip. By booking early, you are likely to secure lower prices and enjoy greater availability, particularly during peak seasons.
3. Consider a smaller car for savings: Smaller vehicles are typically less expensive to rent and easier to maneuver in crowded areas. Mid-size rentals strike a good balance 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 accessible. This also applies to renters over the age of 70. Always verify age requirements before booking.
5. Check fuel policies: Some rentals operate under a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional charges. This option is typically the most favorable. Others may have full-to-empty or prepaid fueling choices, which are acceptable as well, but ensure the car is returned empty in that case.
6. Save on city and airport pickups: You may often incur a surcharge for picking up your rental car at airports, but the convenience might make it worthwhile.
7. Know your payment options: Most car rental companies only accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help prevent unexpected expenses and provides peace of mind should something unforeseen occur during your trip. It’s easy to add car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you’re planning long road trips, look for rentals 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.
