10 tips to save on your car rental in and around Castle Rock

1. Use filters to find the right car: Refine your search by selecting vehicle types and features. Whether you're looking for an SUV for additional space, a convertible for summer fun, or an economical car for budget-friendly travel, utilize the filters on Expedia to discover the ideal option for your journey.
2. Book in advance to help lower costs: Rental prices can vary with demand, so it's wise to reserve your car well ahead of your trip. By booking early, you’re more likely to secure lower rates and enjoy better 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 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 impact renters over the age of 70. 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 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 if you choose this option.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the convenience may justify the extra cost.
7. Know your payment options: Many car rental companies accept only credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and offers peace of mind in case something unforeseen occurs during your trip. It's easy to add car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you’re planning on long road trips, look for rental options that offer unlimited mileage to prevent extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
