There are homes that do not have air conditioning at all, or it is too expensive to run during the day, or only the bedroom has a/c at night.

It is our choice to go to a Caribbean island. However we cannot expect to force our climate expectations or North American reliance upon a/c to be the norm. I'm from Florida. We went to school with no a/c....open the windows. Breeze comes through.

My friend sells generators on Anguilla, Nevis, etc. If you would like the company's contact information I can hook you up. Even after Irma they were swamped with orders. They are reasonably priced. Some units $500. Funny, these same friends visited where I was staying on Mead's Bay...and commented how I was running the air co. It shocked them!
They live in a nice home near Island Harbor...and do not run a/c.
