While Leslie and Gary work on their project, a family comes to the island to inspect the hotel: greedy matriarch Rose Brooks, her husband Freddie, young son Tommy, and pregnant stepdaughter Jane.

They're accompanied by the lustful Linda Sullivan, a young architect hired to provide an estimate for the renovations, and real estate agent Jerry Giordano.
