Look, if you're on a cruise, there aren't too many things worse than hitting an iceberg. That still takes the cake, but there are some things worth avoiding, if you can help it. Like being dead in the water for days without power, as we've seen before. But at this point -- with so many malfunctions -- shouldn't we all just expect it? Fool me once, and all that? So the problem is us, not them. For example, Carnival Cruise Lines just had another power -- and sanitation! -- problem with one of its ships in the Caribbean. When toilets stop working on a vessel with more than four thousand passengers, unpleasantness will ensue.
