They even have the potential to replace cruise liners if properly done. You have to admit, it would definitely be more interesting where scenery is concerned. Kinda like the river cruises offered by Viking?

I would love to cruise the Danube. Rather, I would have before their leaders started unraveling everything there. In no way would I expose my lady to the current horrors taking place in Europe. I might even wind up in jail ................ for killing one of those so called migrants. But before all of this, the Danube would have been marvelous. Now it's a toss up between the Amazon, Mississippi, or the Volga. And those rivers already have far cheaper cruises in place. The pricing is what concerns me about airships. Because we both know that they are floating these teasers for a reason, right?
