Designer Danielle Fennoy and a local Realtor critique three St. Thomas indoor/outdoor luxury renovations to determine which one will get the biggest bang for their buck. First, they check out a home with a hexagon-shaped great room that opens to the deck with a water view. Next, they visit an island getaway with double master suites. And finally, they check out a villa on the edge of a cliff 200 feet above the Atlantic Ocean.
