Yes, we could make a larger cabin with the same weight constraints using modern composite materials.

But even with lighter materials, you would still not be able to accommodate more passengers comfortably. The majority of weight-per-passenger will come from water (which every passenger needs for showering, toilets, food preparation). You would need to land regularly just for passenger hygene reasons. So I still don't expect blimps will be a 'comfortable' alternative to cruise ships.

Random fun fact: The Hindenburg had a grand piano made from aluminium, as a regular piano would have been too heavy.

I think there is usually lots of water in the sky. You could just pipe in a cloud ...

Condensers are going to be heavy, too.

When you have tons of surface area for free and a big temperature difference, I'm sure water condensation can be done in a different way.

Random fun fact 2: They even removed that piano because it was to heavy.

This is truly fascinating. I didn't know that.

Random fun fact-- the only lady on the first round the world zeppelin trip secretly brought on a phonograph!

Cruise ships are absolutely massive. They're floating cities, housing and feeding thousands of people. The new materials would have to be very light indeed to scale from 50 to 5000 passengers.

I would be fine with 50-150 people per module. And then you can maybe meet in air. Combine them or seperate them. Land or go up very high. Drift where the wind blows. The sky is big.
