The Castaways on Gilligan's Island (1979)

The Castaways finally get permanently rescued and they turn their island home into an exclusive resort.

In the second of three additional Gilligan's Island movies following the series, the gang finds a way of getting rescued from the "uncharted desert isle" for a second time through a series of misadventures but comes back to turn it into a tropical resort for uptight mainlanders.
