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

1. Use filters to find the right car: Streamline your search by specifying vehicle type and desired features. Whether you're looking for an SUV to accommodate extra passengers, a convertible for warm-weather drives, or an economy car to keep costs down, utilize the filters on Expedia to identify the best option for your journey.
2. Book in advance to help lower costs: Rental prices can vary significantly based on demand, so it's advisable to secure your vehicle well ahead of your trip. By booking early, you're likely to lock in lower rates and have a wider selection, particularly 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 vehicles offer a solid compromise between price, comfort, and fuel efficiency.
4. Age guidelines: Drivers under the age of 30 might encounter higher deposits or daily fees, and certain vehicle categories—such as SUVs or luxury models—may be off-limits. This can also apply to renters older than 70. Always verify the age restrictions prior to booking.
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 charges. This is typically the most favorable option. Others may provide full-to-empty or prepaid fueling choices, which can be convenient as well. Just ensure you return the vehicle empty in this case.
6. Save on city and airport pickups: There is often an extra fee for picking up your rental car at airports, but the convenience it offers might justify the cost.
7. Know your payment options: Most car rental companies exclusively 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 something unforeseen occurs during your trip. Adding car rental insurance is straightforward when booking through Expedia.
9. Consider unlimited mileage: If you're planning extended road trips, seek rentals that offer unlimited mileage to prevent additional charges.
10. Bring your driver's license and ID: A valid driver's license is mandatory for renting a car.
