The thing that has put us off the last few cruises is realizing how workers on the ships are treated. Twenty years ago, it seemed to us that we would see off duty room stewards and other crew going ashore with their friends, and getting some down time. I know this is subjective, but over time, it seems like giving workers much needed down time stopped happening.
Then fast forward to the present time, my wife and I just don’t want to take a chance getting on a ship because the current new corona virus is so much worse than the Nora virus, which used to be what you worried about on ships.
The very real bummer though is this: there are many hundreds of small ports around the world where people rely on extra income from ships disgorging passengers who spend money. A young engineer in Yalta Ukraine told me that he augmented his income as a scientist from tourist related activities, and it was important income for him.
Yes, the cruise industry should go away, but there will be collateral damage.
