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

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 room, a convertible for summer drives, or an economy car to save on costs, utilize the filters on Expedia to discover the perfect option 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 car well ahead of your travel dates. By booking early, you're more likely to lock in lower rates and enjoy a wider selection, especially during peak seasons.
3. Consider a smaller car for savings: Compact cars typically have lower rental fees and are easier to navigate in crowded areas. Mid-size rentals strike a good balance between affordability, 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 accessible. This can also apply to renters over the age of 70. Always verify the age requirements prior to booking.
5. Check fuel policies: Some rentals operate under a full-to-full fuel policy, which requires you to return the car with a full tank to avoid additional fees. This is often the most economical choice. Other options may include full-to-empty or prepaid fueling, which can also be convenient. Just remember to return the car empty in that scenario.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, though the convenience might 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 protect you from unexpected expenses and provide peace of mind during your travels. It's simple to add insurance when booking through Expedia.
9. Consider unlimited mileage: If you're planning to embark on long road trips, seek rentals that offer unlimited mileage to avoid incurring extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
