10 tips to save on your car rental in Idaho

1. Use filters to find the right car: Refine your search by vehicle type and features. Whether you require an SUV for added space, a convertible for summer drives, or an economy car to save money, utilize Expedia's filters to discover the ideal option for your journey.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it's advisable to reserve your car well ahead of your travel date. By booking early, 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 are typically less expensive to rent and easier to park 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 types of vehicles—such as SUVs or premium models—might not be available. This can also apply to renters aged 70 and above. 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 extra charges. This is generally the best option. Others may offer full-to-empty or prepaid fueling alternatives, which are acceptable as well. Just ensure to 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 added convenience may make it worthwhile.
7. Know your payment options: Many car rental companies only 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 something unexpected occurs during your trip. It's easy to include car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you're planning long road trips, search for rentals that offer unlimited mileage to steer clear of extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
