Raise a glass—Napa Valley is finally out to entice families! This June, the owners of Auberge du Soleil open Solage Calistoga (Calistoga, Calif.; 866/942-7442;; cottages from $425), a resort with 89 high-design cottages plus a kids’ geothermal pool and an activities director who organizes wildlife-watching jeep tours and family cooking classes. Come evening, star-gaze with the resident astronomer, or order in board games—and some Pinot Noir.
