Was me and it was more of a speculative question. The answer will lie in which cruiseco has the highest fixed cost and what their cash position is and what's due debt obligation wise. They'll be fine for the next 60-90 days as they've got the cash from impending cruises (those who are not giving refunds past final payment anyway) but future bookings must be down significantly. Most will probably scrape by but future earnings will be impacted, even if demand mostly but not fully returns (since each marginal cruiser probably costs very little but contributes a lot.).

Cruise ships running out of power or running aground and sinking may be one-ofs but I wonder if this is a the equivalent of a Hindenburg event.
