Having spent a few 12 month years on CC I can't help but notice that no one has mentioned this pertinent detail.
The prevailing winds are from the east 90% of the time. This means that if you are on the front, east, reef side of the island, you will almost never need fans, have sand-fly problems. etc.
If your dwelling is blocked from this constant breeze, by other buildings, etc., the hotter and more uncomfortable you will be.
Location, Location, Location, I cannot stress this enough!
