As a meaningful and needed tool of mass transportation, the days of cruisers are over, yes, but the holiday cruise buisiness is booming - practically all majopr shipyards in the world have filled books, and every major competitor is boosting up his fleet.
Me personally fail to see the fun in spending two weeks on a flying city with shops and shops and shops and more shops and promenades offering more shops and reaching from bow to stern.
If I would consider to make a holiday on the high seas, I would search for an adventure turn on a sailship, at least a very huge yacht. Something liike boarding the gorch fock. but it is unlikely I will ever feel tempted to do even this. Being close to the sea and spend some times in Lübeck and the coast in the Lübeck Bay is good enough for me.
