Marketing the deals on Twitter, Facebook, and their own websites, many hotels are offering discounts. Others are focusing on amenities designed to reduce stress, including spa treatments, kayak lessons, and guided hikes. Starting this month, guests at the Renaissance Pittsburgh Hotel can book "Zen and the Art of Detox" on some summer weekends. The Hotel Monaco Chicago offers anyone who reserves its "tranquility suite" the option to add a "Technology Break." Others with similar packages include the Quincy in Washington, D.C., the Teton Mountain Lodge & Spa in Teton Village, Wyo., the Lake Placid Lodge in Lake Placid, N.Y., and Via Yoga, a Seattle company that specializes in luxury yoga and surfing retreats in Mexico and Costa Rica, including the one Ms. Levy took in April. The services take similar approaches. Typically, they ask travelers to surrender their electronic devices upon check-in. In return, concierges provide them with old-fashioned diversions, from board games to literary classics. (Most, but not all, also yank TV sets and telephones from "detox" rooms.)
