10 tips to save on your car rental in and around Round Lake

1. Use filters to find the right car: Refine your search by selecting vehicle types and specific features. Whether you’re looking for an SUV for extra room, a convertible for summer drives, or an economical car for cost savings, utilize filters on Expedia to discover 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 travel date. By booking early, you’re likely to lock in lower rates and have access to a wider selection, especially during peak seasons.
3. Consider a smaller car for savings: Compact cars are typically more affordable to rent and easier to maneuver in crowded areas. Mid-size cars strike a good balance between cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under the age of 30 may encounter higher deposits or daily fees, and certain vehicle categories—such as SUVs or luxury models—might not be available. This age restriction can also apply to renters over 70. Always verify the age requirements before confirming your reservation.
5. Check fuel policies: Some rental agreements operate on a full-to-full fuel policy, meaning you must return the vehicle with a full tank to avoid additional fees. This is usually the most favorable option. Other rentals may offer full-to-empty or prepaid fuel options, which can also be convenient. Just ensure you return the car empty in this scenario.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the convenience may justify the extra cost.
7. Know your payment options: Most 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 something unforeseen occurs during your trip. Adding car rental insurance when booking through Expedia is a straightforward process.
9. Consider unlimited mileage: If you plan to take long road trips, seek out rentals that offer unlimited mileage to prevent incurring extra charges.
10. Bring your driver's license and ID: A valid driver's license is essential for renting a car.
