10 tips to save on your San Marcos car hire

1. Use filters to find the right car: Refine your search by selecting vehicle type and features. Whether you need an SUV for extra 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 wise to reserve your car well ahead of your trip. By booking in advance, you’re likely to secure better rates and enjoy improved availability, especially during peak 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 offer a good compromise between cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and certain vehicle types—such as SUVs or premium 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 on a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional charges. This is often the most advantageous option. Others may provide full-to-empty or prepaid fueling choices, which are acceptable as well. Just ensure you return the car empty in such cases.
6. Save on city and airport pickups: You may incur a surcharge for picking up your rental car at airports, but the convenience may justify the extra cost.
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 you avoid unexpected expenses and provides peace of mind in case of unforeseen events during your trip. Adding car rental insurance is straightforward when booking with Expedia.
9. Consider unlimited mileage: If you’re planning long road trips, seek rentals that offer unlimited mileage to prevent incurring extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
