I understand there used to be lots of ferry options to Iceland via the North Sea. The one I really wanted to try was from Lerwick. I'm not sure if this ferry went directly to Iceland or if it stopped at the Faeroe Islands. You have no idea how badly I'd want to take this adventure, mainly so I can drive my car around Iceland, but let's not get too far from the point.
I've read a few comments online saying things like it was a 'hellish' journey, or just unpleasant and unpopular. However none of these people elaborated on why the service was poorly received. Could it be the distance? The cold? The price? The choppy seas in winter time? The lack of people on board?
