I don't think we should dismiss the idea just yet, it does have some good points going for it
They might be able to use the large exhibition venue. There is a lift, a car-sized lift that has the space required to carry equipment, bodies from dock level to the deck for the exhibition area.
I saw that area once and was amazed at the size and often wondered how such a space could remain unused when the ship was packed for the impending New years Even events .
As for the rest of the ship, l the elevators are not the size required to move bodies
The Dome building next door used to hold the Spruce Goose, its now partially used for Carnival cruise check-ins. There is a large parking structure next door. The location lends itself to be cut off from the general public. The general cabins would I fear be problematic for hospital use, very limited electrical sockets, awkward sizes and far from ideal bathrooms. But ideal for the staff .
The Sunday Brunch venue with kitchens attached could solve the meal options.
If we put our emotions aside, there are two large spaces, (more if you count the Queen Marys lounges ) with car parking , away from prying eyes , with the ability to have a ship docked next door.
What's everyone else's view? a pipe dream, a reality, a serious option ?
