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 features. Whether you're looking for an SUV for extra space, a convertible for summer drives, or an economy car for budget-friendly travel, utilize filters on Expedia to discover the ideal match 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 before your trip. By booking in advance, you’re likely to obtain lower rates and enjoy better availability, particularly during peak seasons.
  3. Consider a smaller car for savings: Smaller vehicles are typically more affordable to rent and easier to park in crowded areas. Mid-size rentals offer a nice balance of cost, comfort, and fuel efficiency.
  4. Age guidelines: Drivers under 30 may encounter higher deposits or daily surcharges, and certain vehicle categories—such as SUVs or luxury models—might not be available. This can also apply to renters over 70. Always verify the age requirements before making a reservation.
  5. Check fuel policies: Some rentals operate under a full-to-full fuel policy, which means you must return the car with a full tank to avoid additional charges. This is typically the best approach. Other options may include full-to-empty or prepaid fueling, which is acceptable as well—just remember 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 might make it worthwhile.
  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 provides added peace of mind should anything unforeseen occur during your trip. Adding car rental insurance when booking with Expedia is a straightforward process.
  9. Consider unlimited mileage: If you plan to embark on long road trips, look for rentals that offer unlimited mileage to steer clear of additional charges.
  10. Bring your driver's license and ID: A valid driver's license is mandatory for renting a car.
