Heh... freighter travel is another creature entirely. You can't be sure where you're going or when you'll get there. Sometimes itineraries are changed for business reasons. And you really need to be your own entertainment on these..."write-study-contemplate" is right! You won't be pampered and you won't get too much in the way of 'cuisine'. But if you want isolation at a good price, it's one heck of an experience.
