I really liked Biscayne Bay in Miami. Great for a day sail, and you can always go anchor behind Jennifer Lopez's Home just to say you were there
. Yes, the Bahamas, and the beautiful string of pearls called the Keys are great to explore, and right there.
I have never sailed the other places, but look at a chart of Biscayne, and earth google it. Tons of anchorages, and on the weekend hundreds of the beautiful people come out to expose themselves to the sunshine with very little to cover themselves. WELL, at least half are beautiful, and half of them are women
