My wife and I cruise every 2 years or so, but would like to be able to do it full time...
I've heard of a woman (I'm sure there are others) who pays to cruise all year round, on the same ship, no doubt at a discount.
She has her 'own' cabin, knows all the crew, loves new ports of call, and revisiting dozens of others she refreshes her memories and experiences.
If my cypto life eventually allows, we'd like to try lots of cruise ships and pick one and try that for a year, then maybe continue or change ... just to keep exploring all over the world ... returning home to check the mail once a year...nah, maybe not...
