Vacationing on a cruise ship is like being trapped in a floating mall. When they do let you out of the mall, the shore excursions are often trips to a smaller mall.
If you don’t like them, don’t go. Also some are better than others at not feeling like a mall. Some folks enjoy casinos and bars and the ship takes you to new destinations. The ship itself is the core destination and if you don’t go into it thinking than then you won’t enjoy yourself.
Oh yea no argument there. Some of the new ships with LNG are pretty interesting. Another big problem is flying a flag of convenience and bad labor practices.
