Arrivaderci August. With high season safely past, now is the time to visit Venice. Space-seekers will welcome the new SAN CLEMENTE PALACE. Set on a 17-acre isle shared solely by a 12th-century church, the 205-room resort occupies a former Renaissance-era monastery. Wired amenities, plush decor, four restaurants, and two tennis courts update the three-story retreat, which is a mere shuttle-boat ride from St. Mark’s Square. Rooms start at $360. 011-39-041-241-3484,
