We booked a ferry ticket through Direct Ferries, accurately entering our car’s model and exact size. However, the Fast Ferries crew made us pay extra at the port, claiming our VW T4 was a minibus, even though it is officially registered as a private passenger car. During our communication and checking my car papers, Direct Ferries first claimed I had selected the wrong category, then said I had entered incorrect dimensions (which were correct), and ultimately insisted there was no mistake on their side. Unfortunately, this means that even if you enter the correct details, Direct Ferries cannot guarantee that the price you pay will be the final price at the port. I would advise other travelers with similar vehicles against using DirectFerries platform.
