Book Cheap National Car Hire Deals in Foz do Douro, Porto, Portugal

Most car rental companies will ask for a credit card deposit, which is usually held temporarily. Inquire about the specific deposit amount and the process for releasing it once the rental is complete.

Before you book, review the rental agreement for any hidden fees, such as airport surcharges, additional driver costs, or penalties for late returns. Awareness helps in budgeting appropriately.

Many rental firms prefer credit cards and may not accept debit cards for payment. If you're using a debit card, confirm the company's policies before making a reservation.

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.

Take time to read the rental agreement carefully. Understanding the terms can help you avoid unexpected fees and ensure a smooth rental process.

Before returning the vehicle, clarify the return procedures with the rental company. Knowing where to drop off the car and any required inspections can streamline the process.

When hiring a car, especially if you’re arriving in Foz do Douro, Porto by flight, plan for extra time at pickup to accommodate any potential delays. Suppliers like National typically offer a grace period of 30-60 minutes. Providing your flight number can be helpful, but if you’re running late, be sure to call the supplier to inform them.

If you have a specific vehicle model in mind, consider rentals that guarantee the car type you want. This avoids surprises at pickup when you receive an alternative vehicle.
