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

1. Use filters to find the right car: Streamline your search by specifying vehicle type and features. Whether you require an SUV for additional space, a convertible for summer drives, or an economy car to save money, use Expedia's filters to 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 wise to secure your car well ahead of your trip. By booking early, you're more likely to obtain lower rates and enjoy better availability, especially during peak travel seasons.
3. Consider a smaller car for savings: Smaller vehicles typically have lower rental rates and are easier to park in crowded areas. Mid-size cars 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. Renters over the age of 70 could also face restrictions. Always verify age requirements 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 is often the most economical choice. Other options may include full-to-empty or prepaid fueling, which are acceptable as well. Just remember to return the vehicle empty in those cases.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the convenience may make it worthwhile.
7. Know your payment options: Most 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 reassurance in case of unforeseen incidents during your trip. It's easy to add rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you plan on taking long road trips, search for rental options that offer unlimited mileage to prevent additional charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
