Yes, I am almost exactly 2 decades younger, and a grandfather. I have hands-on construction experience from things as small as a dog house, on up to framing forms for 3foot thick concrete slabs for dams, to 3 storey houses.
As a US Army Veteran with disabilities, the government regulates a lot of what I am not allowed to do for a living, so, I live on the lower 25% of income scale, in America.
Realistically, the exchange of preferences also shows optimization for usage and location. Various platforms will eventually be built for different environments and different purposes.
Barges and barge-like hulls are fine for protected waters.
A ship-like hull is necessary for the conditions I am planning for. Of the designs available, I have selected a newer, yet proven design that exhibits the properties I think are necessary for my chosen location. However, a design like I have picked can also be used in protected waters, where a typical barge hull cannot readily deal with the extremes of hurricanes, that I expect to encounter regularly.
The largest Ramform vessel built to date could easily house a traveling resort community, or a good sized commercial IMTA facility and personnel. However, it, too, can be moored in sheltered waters.
The largest barge that I know of, the N’Kossa, is designed around severe weather capabilities, but moored in tension, for stability.
It’s all good informational exchange. I enjoy the experience of trying to explain and refine my personal ideas on the subject.
Two of the largest problems I have seen is the lack of waste handling and the lack of onsite food production.
Plans to transfer sewage while at sea smack of naïveté and shortsightedness… An accident waiting to happen.
Plans to import food also show that lack of foresight.
I am planning for a homestead at sea, you, a resort. Different purposes and different approaches, ultimately achieving residences at sea.
Perhaps my idea of a floating homestead with IMTA will eventually supply your floating resort, helping make for a mutual assistance cooperative existence.
I just feel that without food, there will be a problem supporting the larger groups, whereas a food source first approach makes more sense, to me.
