I met a Canadian couple who said they had no permanent home and instead booked cruises almost full time. They said they spent just enough time in Canada to qualify for health insurance. They claimed their lifestyle was cheaper than renting or home ownership in places they might want to live.Off topic question, how can you take 12 cruise in a year? That average to 1 per month. Say they average to 7 days, so one week out of 4.5, you are in cruise l. How?
