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

1. Use filters to find the right car: Refine your search by selecting vehicle types and specific features. Whether you require an SUV for additional space, a convertible for summer drives, or an economy car for budget-friendly travel, utilize the filters on Expedia to discover the ideal match for your journey.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it’s wise to reserve your vehicle well ahead of your trip. By booking early, you're likely to secure lower rates and enjoy better availability, particularly 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 cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 years old may encounter higher deposits or daily surcharges, and certain 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 before making a reservation.
5. Check fuel policies: Some rentals adhere to a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional charges. This is typically the most advantageous option. Others may provide full-to-empty or prepaid fueling alternatives, which are fine as well; just ensure the car is returned empty in this scenario.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the added convenience may justify the extra cost.
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 you avoid unnecessary expenses and provides peace of mind if something unexpected occurs during your trip. Adding car rental insurance is straightforward when booking with Expedia.
9. Consider unlimited mileage: If you’re planning lengthy road trips, look for rental options that include 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.
