The mini-yellows are my favorite. We went bananas over them when we went to Hawai'i. Only rarely do they show up here in western Canada. They kept well, too. Before we got into our hotel in Hawai'i, we would stop at a grocery and buy a hand, a round loaf of Hawaiian brown sweet bread, small papayas, and dark honey. That, plus milk we kept in the mini-fridge, was our morning breakfast. The little ("lady") bananas would keep for a week.
I think that they are available in the Caribbean, but don't know for certain.
