The first map shows the location of Eleuthera in the Bahamas relative to Florida. Eleuthera is a 1 hour nonstop plane ride from Miami or Fort Lauderdale. It can also be reached from Nassau by plane or fast ferry. Be sure to arrive at Governor's Harbour (airport or dock).
The second map shows Eleuthera Island. "Calypso" is located just south of North Palmetto Point (which is, contrary to the map, located south of Governor's Harbour). It is located just north of the feature shown as Palmetto Point, on the Atlantic ocean side of the island. You should arrive at Governor's Harbor Airport (see "Directions"). There are also airports at North Eleuthera and Rock Sound but these are a long taxi ride from "Calypso". The island is about 110 miles long.
The third map is also rather vague. North Palmetto Point is in the right place, but South Palmetto Point should be on the left ("Caribbean") side of the island.
A much better map has been prepared by Peter Loud.
