10 tips to save on your car rental around Gillette Castle State Park

1. Use filters to find the right car: Refine your search by selecting specific vehicle types and features. Whether you're looking for an SUV for extra space, a convertible for summer drives, or an economy car for budget-friendly options, utilize Expedia's filters to discover the best fit for your journey.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it's advisable to secure your car well ahead of your travel date. By booking in advance, you're more likely to snag lower rates and enjoy greater availability, 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 vehicles strike a good balance between cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 years old may encounter higher deposits or daily fees, and certain vehicle categories—such as SUVs or premium models—might not be available. This can also apply to renters over 70 years old. Always verify the age requirements prior to booking.
5. Check fuel policies: Some rentals operate on a full-to-full fuel policy, which requires you to return the vehicle with a full tank to avoid extra charges. This is typically the most economical choice. Other options may include full-to-empty or prepaid fueling, which are also acceptable; just ensure you return the car empty in these cases.
6. Save on city and airport pickups: Picking up your rental car at the airport often incurs a surcharge, but the convenience it offers may justify the extra cost.
7. Know your payment options: Most car rental companies exclusively accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provide peace of mind should anything unforeseen occur during your trip. It's simple to add rental insurance when making a reservation through Expedia.
9. Consider unlimited mileage: If you're planning on taking long road trips, seek out rental options that offer unlimited mileage to steer clear of additional charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
