Same here, I keep travelling alot, not much of seagoing ships here on the river rhine and I am simply not into river-boats, hehe !! So I keep travelling by ferry and others. Been after that to Rotterdam, also took photos and travel to Norway after that, Oslo and a few other places, too.
I think about writing a little travel-report on the King of Scandinavia here, not sure if anyone is interested and ok, to describe the ship which I travelled first on, when it was still the "Val de Loire" and which has changed, in some ways, but in generally to the better. DFDS service, better than Brittany Ferries service is ONE thing just. Then comes better food, Danish pastry and and and... :-D
