Maui is the Polynesian demigod who taught people how to make fire, and the storied Hawaiian island where Mario built a private spa retreat on Kaanapali Beach. Julian spent much of his first year there, and the family’s associations include scuba diving, swimming with turtles, listening underwater to whale songs, flowers, fruit, and fresh fish. The heat and clean, clear water of this tropical paradise inspired the elegant Maui hot tub.
