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

1. Use filters to find the right car: Refine your search by selecting vehicle type and specific features. Whether you're looking for an SUV for added space, a convertible for summer outings, or an economy car for budget-friendly travel, 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 with demand, so it's advisable to secure your vehicle well in advance of your trip. By booking early, you're more likely to find lower rates and greater availability, particularly during peak travel seasons.
3. Consider a smaller car for savings: Smaller cars are typically more affordable 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 may encounter higher deposits or daily surcharges, and certain vehicle categories—such as SUVs or premium models—may not be available. This can also apply to renters over 70. Always verify the age requirements before making your reservation.
5. Check fuel policies: Some rental agreements require a full-to-full fuel policy, meaning you must return the vehicle with a full tank to avoid additional fees. This is typically the most economical option. Others may provide full-to-empty or prepaid fueling choices, which are acceptable as well; just remember to return the car empty in that scenario.
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: Many car rental companies primarily accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provides peace of mind in case of unforeseen incidents during your trip. Adding car rental insurance when booking with Expedia is a straightforward process.
9. Consider unlimited mileage: If you're planning an extended road trip, look for rental options that offer unlimited mileage to prevent incurring additional charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a vehicle.
