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.
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.
