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 selecting vehicle type and specific features. Whether you’re looking for an SUV for extra room, a convertible for summer drives, 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 rates can vary based on demand, so it's wise to reserve your vehicle well ahead of your trip. By booking in advance, you're more likely to secure lower prices and have a greater selection, particularly during peak travel seasons.
3. Consider a smaller car for savings: Compact cars are typically more affordable to rent and simpler to park in crowded areas. Mid-size rentals strike a good balance between cost, 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 70 years old. Always verify the age restrictions prior to booking.
5. Check fuel policies: Some rental agreements require a full-to-full fuel policy, which means you must return the vehicle with a full tank to avoid additional fees. This is generally the most favorable option. Other policies may offer full-to-empty or prepaid fueling, which can also work, but ensure that the car is returned empty in that case.
6. Save on city and airport pickups: You may incur a surcharge for picking up your rental car at airports, but the convenience might justify the extra cost.
7. Know your payment options: Most 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 any unforeseen events during your trip. It’s easy to add this insurance when booking with Expedia.
9. Consider unlimited mileage: If you plan to take long road trips, look for rental options 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.
