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

1. Use filters to find the right car: Refine your search by vehicle type and specific features. Whether you’re looking for an SUV for added space, a convertible for summer fun, or an economical car for budget-friendly travel, utilizing filters on Expedia will help you identify 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 secure your car well ahead of your trip. By booking early, you’re likely to lock in lower rates and enjoy a wider selection, especially during peak travel seasons.
3. Consider a smaller car for savings: Generally, smaller cars are less expensive to rent and easier to maneuver in crowded areas. Mid-size rentals strike a good balance between price, comfort, and fuel efficiency.
4. Age guidelines: Drivers under the age of 30 may encounter higher deposits or daily surcharges, and specific vehicle types—such as SUVs or luxury models—might not be available. This can also apply to renters over 70 years old. Always verify the age requirements prior to booking.
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 is typically the best choice. Other options may include full-to-empty or prepaid fueling, which are acceptable as well. Just be sure to return the car empty in those cases.
6. Save on city and airport pickups: There’s often an extra fee for picking up your rental car at airports, but the added convenience may make it worthwhile.
7. Know your payment options: Many car rental companies exclusively 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 something unforeseen occurs during your trip. Adding car rental insurance when booking through Expedia is straightforward.
9. Consider unlimited mileage: If you plan on taking long road trips, search for rentals that offer 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.
