Cheap Budget Car Hire Deals at Sao Bento Train Station, Porto

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.

Many rental companies require payment by credit card and may not accept debit cards. If you only have a debit card, check the rental company's payment policies in advance and look for suitable options.

When renting a car, it's crucial to understand the different insurance options available. Selecting the right insurance can protect your finances in case of an accident. Common options include Collision Damage Waiver (CDW) and liability insurance, so make sure to confirm the required coverage with the provider.

Before traveling, familiarize yourself with local driving laws and regulations. This can help you avoid fines and ensure a safe driving experience.

When renting a car, understand the fuel policy. A 'Full-to-Full' policy means you return the car with a full tank, while 'Same-to-Same' means you return it with the same level of fuel. Full-to-Full is often more cost-effective.

Some rental companies offer a free tank of fuel with your rental. Be sure to understand the terms, including how much fuel you need to return the car with and any potential fees for not meeting these conditions.

If you have a specific vehicle in mind, opt for rentals that guarantee your chosen car type. This ensures that you receive the vehicle you expect, rather than being offered an alternative.

If you're looking for more comfort or features, inquire about upgrade options at the rental desk. Sometimes, upgrades are offered at a discounted rate at pickup.
