The Guggenheim’s closing of its gallery in the Venetian Hotel Marks an end. The philosophy of the Guggenheim Hermitage had been to send visitors the message that “you don’t have to know anything about this to enjoy it; we’re not going to make you feel intimidated,” but without dumbing down the art. Nonetheless, while “we broke even and even made money sometimes,” the museum director said, attendance had dropped the last two years. “Seven years is dog years in Las Vegas. All good things come to an end.”
