A couple from Florida, John and Melody Hennessee, sold their home and belongings to travel the world by living on a cruise ship. They found it more affordable than living on land and have fully booked trips until December 2024. Their current expenses are estimated to be half of what they were on land, with no mortgage or home-related expenses. They plan to build a cruise ship called Villa Vie Odyssey, an all-inclusive residential cruise, which will be their home for at least 15 years.
