The “Rock Star” program, offered at the upscale Rock Resorts chain, provides experts from specific fields to share their knowledge with a group. For example, the Lodge and Spa at Cordillera, in Edwards, Colo., employs a snowshoeing expert to guide guests on moonlit tours. The “Cheese Whiz” — a lecturer at La Posada de Santa Fe Resort and Spa, in Santa Fe, N.M. — offers a slice of his knowledge of cheese presentation, aging and history.
