10 tips to save on your car rental in and around Southern Idaho

1. Use filters to find the right car: Refine your search by vehicle type and specific features. Whether you're looking for an SUV for extra space, a convertible for summer adventures, or an economical car for budget-friendly travel, utilize the filters on Expedia to discover the perfect match for your journey.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it's wise to secure your reservation well ahead of your trip. By booking in advance, you're more likely to lock in lower rates and enjoy a wider selection, particularly during peak travel seasons.
3. Consider a smaller car for savings: Smaller vehicles are typically more affordable to rent and easier to maneuver and park in crowded areas. Mid-size rentals offer a solid balance of cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and certain vehicle categories—such as SUVs or luxury models—might not be available. This can also apply to renters older than 70. Always verify the 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 cost-effective choice. Others may offer full-to-empty or prepaid fueling options, which are acceptable as well—just ensure that you return the car empty in that case.
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 accept only credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provides peace of mind if something unforeseen occurs during your trip. Adding car rental insurance when booking through Expedia is straightforward.
9. Consider unlimited mileage: If you're planning long road trips, look for rentals that offer unlimited mileage to prevent incurring extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a vehicle.
