I'm seeing many attractive hillside rentals that don't offer air conditioning, or if they do, it's only in the sleeping areas. Owner claim a ceiling fan and ocean breezes are adequate to keep you cool in the daytime.
Having grown up in Northern California, I'm not very heat tolerant (my ideal summer temp range is 74-84 degrees tops with little humidity) so I don't want to be miserable. On the other hand, I realize we're on a tropical island and we'll be spending lots of time outdoors anyway so it many not be as big a deal as I think. Will we be reasonably comfortable with ceiling fans in late July?
