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

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 added space, a convertible for summer drives, or an economical car for budget-friendly travel, utilize filters on Expedia to discover the best options for your journey.
2. Book in advance to help lower costs: Rental rates can vary based on demand, so it's advisable to reserve your vehicle well ahead of your trip. By booking early, you’re more likely to secure lower prices 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 maneuver in crowded areas. Mid-size rentals strike a good balance between price, 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 the age of 70. Always verify the age requirements prior to making a reservation.
5. Check fuel policies: Some rental agreements require a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional fees. This is often the most convenient option. Other policies may offer full-to-empty or prepaid fueling, which can also work; just ensure you return the vehicle 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 added convenience may justify the cost.
7. Know your payment options: Many car rental companies primarily accept credit cards for 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. It's easy to add this coverage when booking through Expedia.
9. Consider unlimited mileage: If you’re planning extensive road trips, seek out rentals that offer 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.
