When the Ritz-Carlton, Lake Tahoe, opened at the Northstar ski resort in 2009, it won acclaim as the region’s first five-star hotel. But its fortunes tumbled due to a double downturn: the economy and snowfall. Now that both droughts are apparently over, the Ritz is making a new splash with the debut of its Lake Club. Open since late June, the private lakefront facility in Tahoe Vista costs guests an additional $250 per adult to use (free for accompanying children). In return, guests have access to a private pier, a lawn with lounge chairs, a hot tub and, in the two-story clubhouse, spa-style locker rooms, a living room/lounge and upstairs deck.
