The Silvertree Hotel & Conference Center in Snowmass, Colorado, will fly the Westin flag next winter following a multimillion-dollar transformation. The resort’s redesigned 254 guestrooms and suites will offer slope-side views, while new restaurant Snowmass Kitchen has ski-in/ski-out access. The property’s upper pool will be redeveloped into a landscaped space suited for outdoor events; the lower pool will be rebuilt to include two hot tubs. Additional upgrades are planned for the fitness center and 20,000-square-foot conference center.
