Well, I have spent some considerable time hearing people rave about cruises, lots of rather braggy Facebook posts, etc. I never saw the point. The antithesis of how I like to travel - simply & really dig down & get to know people & places. So Iwas finally persuaded to go on a short, bargain cruise -3 days, £80 going from Dover to Copenhagen to Rostock.
Well, it wasn't as bad as Ithought it would be - the ship absorbed the many passengers pretty well; I couldn't fault the service or quality, but I don't get it, really. I was quite bored, and the shore stops are too short to get any meaningful insight into local culture. I suppose if you like cheesy entertainment, Bingo, gambling, serious over-eating & a very artificial atmosphere, it's heaven.
Doubtless I will be flamed.
