Beware truckers - Greek, Italian, Bulgarian, Turkish... they're all the same - that make everyone else wait in the check-in queue while they try to wangle themselves a single cabin instead of the berth in a shared cabin that's all they're entitled to, are allowed to board and drive off before everyone else (everyone else has to wait), and monopolise the bar. Usually they aren't allowed to drive on Sundays, so if possible take a ferry arriving on Saturday evening or Sunday morning. They get less truckers, because the truckers don't want to have to wait in a port area for twenty-four hours until they can set off grinding down the motorway again. This applies to all Superfast ferries, not only Superfast XI. And it may be the same with other lines.
