I suppose you can rent these.
I noticed at least one has a solar panel. They do have a generator for some of their electrical needs.
The other side of the "wall"
.
Before I forget - while there was not tons of it - there appeared to be some glass now and then, so watch where you step...

Snorkeling was better than I thought it would be.
A small barracuda
A large stingray
There was coral and sea fans and fish and more...
