I think it will be interesting to see if the trend towards ever-larger ships, with ever larger numbers of bodies on board continues. I can't be the only one thinking this seems a really bad idea now, and they'd be the ships I'd avoid like the plague (pun intended).
I realise that economies of scale mean that a smaller ship will be more expensive to travel on, but has anyone actually tried to put their mind to a new "clean sheet of paper design" of a smaller (1000 passenger maybe) mass-market cruise ship and how economically it could be built and run?
I realise a huge proportion of the population just won't care, and will want back onto their cheap cruises ASAP, but there will be a lot others like me.
