personally, I find the difference between 28 and 32 noticeable; but I didn't mean to suggest they have anything like a cold season; sorry if I didn't make that clear. Europe and (especially) North America do, which is why all the snowbirds head for the Caribbean then.
In terms of local colour you might want to choose between British Caribbean (Antigua, Barbados, BVI), French Caribbean (Martinique, St Barts) and Dutch (Aruba, Curacao); but their cultural differences have become fairly homogenised.
