The Zeppelins were not squalid or horrible, but they were incredibly spartan and not at all Luxury compared to what a cruise ship can do with a lot of mass. Here's a reproduction Hindenburg passenger cabin[1], compare with a cabin on a luxury cruise ship[2]. They're optimised for low mass more than comfort.
Then a reproduction lounge on the Hindenburg[3], compare with any of these on a cruise ship[4]. Ships are roughly as luxurious as you want to spend money to get, rivalling any hotel. (Water is ~750x denser than air, does that mean it can buoy up 750x more luxury per passenger for the same displacement vessel?)
