This looks interesting!
Cabins run the gamut from 13 square feet “Virtual Inside” staterooms – which start at $29,999 per person per year, coming out at $179,994 for the three-year trip for two people – to Balcony Suites, which are double the size and go up to $109,999 per person. The cheapest outdoor cabin costs $36,999 per person.
I don't think 13 square feet is correct. I think they meant 130 square feet. The zero makes a big difference.
