10 tips to save on your car rental around Castle Rock State Park

1. Use filters to find the right car: Refine your search by selecting vehicle type and desired features. Whether you need an SUV for extra space, a convertible for summer enjoyment, or an economy car for budget-friendliness, utilize the filters on Expedia to discover the best option for your journey.
2. Book in advance to help lower costs: Rental prices can vary due to demand, so it's advisable to reserve your car well ahead of your trip. By booking in advance, 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 typically come with lower rental costs and are easier to park 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 surcharges, and certain vehicle categories—such as SUVs or premium models—might not be available. This can also apply to renters over the age of 70. Always verify age requirements before making a reservation.
5. Check fuel policies: Some rentals operate under a full-to-full fuel policy, which means you must return the car with a full tank to avoid additional fees. This is usually the most advantageous option. Others may provide full-to-empty or prepaid fueling alternatives, which are also acceptable. Just remember to return the car empty in such cases.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the added convenience might make it worthwhile.
7. Know your payment options: Many car rental companies primarily accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unnecessary expenses and provide peace of mind in case of unexpected events during your trip. It's easy to add car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you plan on taking long road trips, search for rentals that offer unlimited mileage to prevent extra charges.
10. Bring your driver's license and ID: A valid driver's license is required to rent a vehicle.
