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

1. Use filters to find the right car: Refine your search by specifying vehicle type and features. Whether you need an SUV for additional space, a convertible for summer drives, or an economy car for budget-friendly travel, utilize the filters on Expedia to identify the best option for your journey.
2. Book in advance to help lower costs: Rental rates can vary based on demand, so it's advisable to secure your car well ahead of your trip. By booking early, you’re likely to obtain lower prices and enjoy a wider selection, particularly during peak travel seasons.
3. Consider a smaller car for savings: Compact cars are typically less expensive to rent and easier to maneuver and park in crowded areas. Mid-size vehicles offer a favorable balance between 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 premium options—might not be available. This can also impact renters over 70 years old. Always verify the age restrictions before making a 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 fees. This is generally the most favorable option. Others may provide full-to-empty or prepaid fueling choices, which are acceptable as well; just ensure you return the car with an empty tank in this case.
6. Save on city and airport pickups: Picking up your rental car at the airport often incurs a surcharge, but the added convenience may justify the cost.
7. Know your payment options: Many car rental companies exclusively accept 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 simple.
9. Consider unlimited mileage: If you plan on taking long road trips, look for rental options that offer 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.
