Cruise market is quite old anyway, so maybe the next generation will have enough time to recover/ forget?
It's a horrible situation for the entire travel/ tourism/ aviation market really, because they have almost zero cash reserves, and so many local and non-local interdependencies that all need eachother, and all need cash flowing - from the airlines, through to the hotels in Spain, to the fella selling melons on the beach in Denia.
I reckon 25% of the industry could disappear, at least in 2020.
When looking at carbon emissions and the likes, eventually eliminating the cruise industry would be a big step. Obviously planes are need for getting people around the world and cargo ships are necessary but cruise ships are massive pollutants. Also I can't think of any holiday I'd hate more than going on a cruise.
