This is the first time I have heard the "fuel cost per cabin" of a cruise ship, but even the pre-2026 price of $1,800 per month underlines just how much carbon cruise ships emit -- if we use airline ticket prices as a guide, they might emit somewhat less per passenger for the same distance traveled (!) but an enormous amount relative to living on land. https://www.bbc.com/news/articles/cwj342k62exyo
