Book Cheap AVIS Car Rental Deals in Foz do Douro, Porto, Portugal

Make sure you know the details of the roadside assistance included with your rental. This is crucial in case of breakdowns or accidents.

Before finalizing your booking, check if the rental company offers free cancellation. This can provide peace of mind if your travel plans change unexpectedly.

Research any toll roads on your travel route and understand the payment options. Some rental companies provide toll transponders for convenience.

If you plan to have someone else drive, check if the rental company permits a second driver and whether there are extra fees involved. Some may offer free additional drivers under specific 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.

Before renting a car, check if your personal car insurance covers rental losses. Many personal auto insurance policies and credit cards offer coverage for rentals, which could save you from extra insurance fees.

Note that some rental companies impose age restrictions or additional fees for drivers under 25. Always verify the age policy when booking.

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.
