John and Melody Hennessee plan to spend the rest of their lives cruising around the world and they reckon it could be as much as half as expensive as their life on land. The couple sold almost everything they owned three years ago, including their main business and their home, and bought a motorhome to travel around the US. But then John, 76, got tired of driving, says Melody. Then they saw an advert on Facebook for a 274-day cruise with Royal Caribbean, and their journey to a permanent life at sea began. The pair are currently cruising around the Dominican Republic as part of the latest in a series of long-term sailings, which have taken them to places including Australia, New Zealand, and the South Pacific. "We now have a telephone bill, a ship bill, and a few credit cards bills for when we go ashore, but that's it," says John. At the moment, their life is planned in monthly chunks, as they hop from ship to ship and they are booked up to December 2024. But soon they will be taking up a more permanent residence on Villa Vie's residential cruise ship where as many as 30% of those on board will be permanent residents.
