Your answer depends on your ultimate Antarctic destination, the boat you sail in, its speed and capabilities, and the weather and sea sailing conditions on your route.
One example of a cruise leaving from Florida and going to the Antarctic is below. In this cruise, the ship gets to Antarctica a month after leaving. Obviously, it would be faster if you went straight there, but finding a ship that will do that would probably have to be chartered, since the regular cruise lines will visit other places on the way... and very few of them leave for the Antarctic from Florida.
