The state’s first and only St. Regis—a brand renowned for its opulence and service—opened in 2009, following a multimillion-dollar transformation of the Princeville Hotel. The dramatic cliffside layout didn’t change: You enter on the ninth floor, with a dazzling panorama of Hanalei Bay and Makana (the “Bali Hai” mountain) across the airy lobby and an elevator to take you down to the narrow but pleasant sandy beach and 5,000-square-foot infinity pool. The spacious (540 sq. ft. and up) rooms still feature extra-large bedroom windows as well as “magic” bathroom windows, which toggle between clear and opaque, but no balconies. Families should consider the Ocean View Terrace rooms, which open onto the pool level. A welcome sheen of sophisticated Hawaiiana infuses the resort, typified by the 11,000-square-foot Halelea Spa, which combines traditional Hawaiian healing practices and local botanicals with Western treatments.
