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 the vehicle type and specific features that suit your needs. Whether you're after an SUV for additional space, a convertible for those sunny days, or an economical car for budget-friendly travel, utilise the filters on Expedia to discover the ideal option for your journey.
  2. Book in advance to help lower costs: Car rental prices can vary significantly based on demand, so it's advisable to secure your booking well ahead of your trip. By reserving early, you're more likely to obtain lower rates and enjoy a wider selection, particularly during peak travel seasons.
  3. Consider a smaller car for savings: Compact cars are typically more affordable to rent and easier to manoeuvre in busy urban environments. Mid-size vehicles strike a satisfactory balance between cost, comfort, and fuel efficiency.
  4. Age guidelines: Drivers under the age of 30 may encounter higher deposits or daily surcharges, and some 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 the age restrictions before finalising your booking.
  5. Check fuel policies: Some rental agreements stipulate a full-to-full fuel policy, meaning you must return the vehicle with a full tank to avoid incurring extra charges. This is usually the most advantageous option. Others may provide full-to-empty or prepaid fuel options, which can also be convenient. Just ensure you return the car with an empty tank in this case.
  6. Save on city and airport pickups: There is often a surcharge for collecting your rental car from airports, but the added convenience might justify the extra cost.
  7. Know your payment options: Many car rental companies predominantly accept credit cards as a form of payment.
  8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and offers peace of mind should any unforeseen events occur during your trip. Adding car rental insurance when booking through Expedia is straightforward.
  9. Consider unlimited mileage: If you're planning extensive road trips, seek out rentals that include unlimited mileage to prevent incurring additional charges.
  10. Bring your driver's license and ID: A valid driver's licence is mandatory to rent a vehicle.

To escape any unwanted surprises on pickup, make sure you know if any extra charges apply to you.
Can I drive in Boulder with my current driver's license?
If you don't have a license issued in the United States, you might need to organise an International Driving Permit (IDP) in your country of residence before renting a car. If you find that an IDP is required, be aware that you'll also have to show your current valid driver's license and your passport or other form of ID. Lastly, the credit card that was used to rent the vehicle must match the name on your license and passport in order to finalize your car rental. Some additional requirements for renting a car in the U.S. Are:
  • Age restrictions: You must be at least 25 in most states to be able to rent a car, although in some places the minimum age is 21. We recommend checking local rules and regulations, and with the car rental company before you book to understand all the terms and conditions.
  • Driving limitations: Make sure you read the fine print before you drive off the lot so you can avoid unnecessary fees. When renting a car in the U.S, it's usually prohibited to cross country borders into Canada or Mexico, drive onto ferries or go off-roading with a rental car. We recommend reading all the rules and regulations before you book!
