 Are cruise ships the new retirement homes? More and more people are discovering that living on a cruise ship can be cheaper than assisted living. I mean, everything you need is covered. Food, housing, entertainment, and decent medical care. And the cold cruisers movement isn't slowing down. Some cruise lines are hopping on the trend offering world cruises lasting more than 50 days at a time. Some as little as $50 a day, which is far cheaper than senior living. Sure, you might be living in a tiny cabin and have to deal with sea sickness from time to time, but you would be seeing the world instead of cooped up inside all day. Would you ditch the retirement home and ride the cruise ship wave?
