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

  1. Use filters to find the right car: Refine your search by selecting vehicle types and features. Whether you need an SUV for added space, a convertible for warm weather, or an economy car for budget-friendly options, utilize the filters on Expedia 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 before your trip. By booking in advance, you’re more likely to access lower rates and better availability, especially during peak travel seasons.
  3. Consider a smaller car for savings: Smaller vehicles typically come with lower rental costs and are easier to maneuver in crowded areas. Mid-size cars strike a good balance between price, comfort, and fuel efficiency.
  4. Age guidelines: Drivers under 30 may encounter higher security deposits or daily fees, and certain vehicle categories—like SUVs or luxury models—might not be available. This can also apply to renters over 70 years old. Always verify age requirements before making a reservation.
  5. Check fuel policies: Some rental agencies require a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional charges. This is usually the most favorable option. Others might offer full-to-empty or prepaid fueling alternatives, which are also acceptable; just ensure you return the car empty in that scenario.
  6. Save on city and airport pickups: There’s often a surcharge for picking up your rental car at airports, but this may be justified by the added convenience.
  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 in case something unforeseen occurs during your trip. Adding car rental insurance is straightforward when booking with Expedia.
  9. Consider unlimited mileage: If you plan on taking long road trips, look for rental options that include 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.
