Your belief that "Being on a cruise is supposed to be a luxury experience where you have no worries" shows a lack of realism irrespective of what you claim the brochures promise.
1. There needs to be a reality check. Sensible people have realistic expectations. Not all cruises are the same. The main differences include the staff / passenger ratio. Unexpected things go wrong. Even on a 6 star line things go wrong and you have to be patient. To say "that should have been known at check in " and use that to justify mounting a campaign demostrates a lack of balance.
2. Asking him / her to wait was not fishy. They upgraded him. They possibly wanted to see what the best available was going to be. There are "no shows" even on cruises. This strategy worked because they were upgraded from inside to sea view. To trivialise this shows a lack of reality and appreciation and balance.
Do you have any idea what you are talking about? A Lack of reality and balance? I didnt mount any campaign, I've just stated that sending a customer to a room you know is full of water is a bad idea.
