[quote="Vlad"][quote="Admiral John Byng"]Also, there are major design differences between a "cruise ship" like this and a "liner" e.g. QM2. The latter has different structural requirements to do with maintaining speed and seaworthiness in a heavy seaway (e.g. Atlantic crossing). The ships designed for summer cruisers in the Caribbean are built lighter.[/quote][/quote]
The seaworthiness demands for cruise ships are in fact very strict and they have to be able to survive extreme wind and waves, also in case of a power failure. Plus, wave slamming is of particular concern, both bow wave and stern slamming (they tend to have flat after bodies).
So they can all do this

Note that these cruise ships are much much larger than the older liners and, similar to these very large container ships, are naturally a bit more flexible than shorter hulls. I've been told that modern cruise ships do not have hallways from end to end so that you can see them flex!

As fair weather ships, cruise liners' superstructure are lightly built.

Well, on a liner the hull proper has a much greater freeboard, with the "squishy" cabins only starting higher up.

They are an eye-sore, a nuisance for those who are swarmed by their tourists (think of Venice, Barcelona, ...), and an environmental threat (because, for instance, they have to run their generators with cheap sulfurous oil, because harbours don't have enough energy to supply them), etc.

Crazy ship.
My wife and I prefer the much smaller cruise liners, 600 - 1000 passengers, not these floating cities.

ThrillistQuote: The World's Biggest Cruise Ship Just Set Sail, and It's Straight-Up Bonkers Thrillist Matt Meltzer 6 hrs ago
It had been a while since I’d played Aliens vs. Robots. But nothing really bonds you with a group of complete strangers like strapping on a set of laser tag vests, running around in total darkness, and aimlessly shooting at people you’re not sure are your teammates or your enemies. So this was how I figured I’d make friends aboard Royal Caribbean’s new mega-ship, Symphony of the Seas.
I’d been tracking this amusement park on the high seas for a while now, anticipating the unknown once it actually launched. The new ship -- the world’s largest -- also boasts the world’s largest glow-in-the-dark laser tag arena. And as I found myself sailing alone I teamed up with a group of Chinese journalists, who spoke about as much English as I did Mandarin. We did find that the language of laser tag is universal, and as we stumbled around this massive, dark course together, shooting at whatever we could find, we laughed like kids. Then we did what new friends always do: tallied our kills together. D'awwww.
(...SNIPPED)
