Last August DFDS put me in a queue which then boarded up a ramp which then led left up a "tunnel" entrance to the car deck and right to the deck with trucks and vans. I just stopped at his fork and refused to follow the other cars where there clearly was not enough height for my LWB with pop top. They soon moved the cones and waved me right so the rest of the cars could board - the queue was stopped and quite long by then! No comments nor questions asked! I had booked as a large car and nobody said a word.
