You want warm. If you put them some place cold they have to have heat. If it is warm you just have to have shade. Midway would require water rationing food would be expensive and housing would have to be imported as there is literally nothing there but a runway.
The Aleutians are also less remote and easier to see family and friends.
They also have scenery.
I want a location where they have nothing to look at except the ocean. No where to go except to bed and no cultural or normal leftist type activities. Make them home school their kids in the middle of nowhere.
There are no bears on Midway and other than typhoons it is not a dangerous place but it is very, very remote.
I lived in Saudi Arabia for a bit in the nineties.
That is why I want them someplace cold.
They would never acclimate to the cold.
And no, they dont have to have heat, insulate the building well and pack them close together. If you ever do decide on heating, 55 degrees is all you ever need.
Visitors? That’s what the coast guard is there to prevent.
I would choose Semisopochnoi in the Rat group. Its pretty lifeless, and if the there were a volcanic eruption well, too bad those things happen.
