10 tips to save on your San Marcos car hire

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 added space, a convertible for summer drives, or an economy car for budget-friendly travel, utilize the filters on Expedia to find the perfect fit for your journey.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it's wise to reserve your car well ahead of your trip. By booking early, you're more likely to secure lower rates and enjoy better availability, particularly during peak seasons.
3. Consider a smaller car for savings: Smaller vehicles typically come at a lower rental cost and are easier to maneuver and park in crowded areas. Mid-size options strike a good balance between affordability, comfort, and fuel efficiency.
4. Age guidelines: Drivers under the age of 30 may encounter higher deposits or daily surcharges, and certain vehicle categories—such as SUVs or luxury models—may 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 under a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional fees. This is generally the most favorable option. Others may provide full-to-empty or prepaid fueling choices, which are acceptable as well—just ensure you return the car empty in that scenario.
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 as a form of payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provides peace of mind if something unforeseen occurs during your trip. Adding car rental insurance is simple when booking through Expedia.
9. Consider unlimited mileage: If you plan on taking long road trips, seek rentals that offer unlimited mileage to steer clear of extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
