  • Business Insider spoke with three people who live on cruise ships for at least half the year.
  • One remote worker spent 300 days living on a cruise ship and said it cost as much as his apartment.
  • Another cruise ship resident lives for free as a "wife on board."

As the urge for a simpler way of living grows, some cruise companies are offering condos starting at $100,000. On these ships, people can travel around the world every 3 ½ years. For those who don't have hundreds of thousands of dollars to spend, there are other ways to make a cruise ship your home.
