10 tips to save on your car rental in and around San Antonio

1. Use filters to find the right car: Refine your search by selecting vehicle types and features. Whether you're looking for an SUV for extra room, a convertible for summer drives, or an economy car for budget-friendly travel, utilize the filters on Expedia to discover the ideal option for your trip.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it’s advisable to reserve your car well ahead of your trip. By booking early, you’re likely to secure better rates and enjoy a wider selection, especially during peak travel seasons.
3. Consider a smaller car for savings: Compact cars are typically more affordable to rent and easier to park in crowded areas. Mid-size rentals 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 age requirements prior to booking.
5. Check fuel policies: Some rental agreements stipulate 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 advantageous option. Other policies may include full-to-empty or prepaid fueling options, which can also be convenient—just make sure to return the car empty in that case.
6. Save on city and airport pickups: Picking up your rental car at the airport often incurs a surcharge, but the convenience may make it worthwhile.
7. Know your payment options: Many car rental companies only accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help prevent unexpected expenses and provide peace of mind in case of unforeseen events during your trip. It's simple to add car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you plan on taking long road trips, seek out rentals that offer unlimited mileage to avoid additional charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
