Book Cheap Hertz Car Hire Deals in San Francisco, Madrid, Spain

Research fuel prices in the area where you'll return the vehicle. Filling up at a local station may be cheaper than paying for fuel through the rental company, especially if they charge higher rates.

Before leaving the rental location, inspect the car for any existing damage and ensure it’s documented. Take photos if necessary to avoid disputes when returning the vehicle.

If you are travelling to San Francisco, Madrid and considering hiring a car, choosing an in-terminal car hire supplier can save you time and hassle. Suppliers like Hertz have locations right at the airport, allowing you to avoid shuttle buses or meet-and-greet services and ensuring a quicker and more convenient pickup.

Before booking, review the rental agreement for any hidden fees such as airport surcharges, additional driver fees, or late return penalties. Understanding these can help you budget more effectively.

If you're looking for extra comfort or features, ask about upgrade options at the rental counter. Often, discounted upgrades are available at pickup.

Familiarize yourself with the fuel policy for your rental. A 'Full-to-Full' policy means returning the car with a full tank, while 'Same-to-Same' indicates you return it at the same fuel level. Full-to-Full is usually more economical.

If you're traveling with pets, verify the rental company's pet policies beforehand. While some allow pets, there might be specific fees or limitations.

Before renting, check if your personal auto insurance extends to rental cars. Many policies and credit cards offer rental coverage, helping you save on insurance costs.
