I booked a ticket from Wellington to Picton. At the time I didn't know exactly what car I would be driving (it would depend on the rental company) but according to their website that would not be a problem as I would be able to amend it when I have the car available. When I received the car and tried to amend the particulars in their website they replied that the amendment was not possible. I contacted the operator and could get a ticket for the same day and time as my original one. Then I asked for a cancelation of the ticket with DirectFerries (according to their website that would be possible for a fee). They replied that cancelation was not possible (even after I insisted that according to their website it was possible). So I got ripped of of the value of the ticket... My strong advise: DO NOT DEAL WITH THIS COMPANY - IT'S A SCAM.
