The best is a car rental company, which offers the possibility to pick you up on
arrival and take you outside the airport to pick up your rental car, thus avoiding all the crowds and traffic of the terminal. Doesn't it seem ideal? It is... the ease of coming and to be picked up, and when returning the car, they bring you back without having to worry about anything but being on time for your flight is priceless and is something that some companies offer for free, but not all.
