With a name that means "house befitting heaven" in Hawaiian, Halekulani is a serene and romantic oasis in the center of Waikiki. The luxury hotel owes its soothing ambience to its elegant monochromatic décor—seven shades of white—and to the calm-inducing space in its 453 rooms, which are 500-to-700 square feet, with most offering at least a partial ocean view. Truly spectacular are Diamond Head Ocean Front rooms, which like the hotel's suites, provide panoramas of Oahu's famous landmark. Couples looking to unwind can soak up the South Pacific sun on the beach or at the shimmering glass-tile mosaic pool, enjoy a lomi lomi massage for two at SpaHalekulani, and experience traditional Hawaiian music, dance and appetizers at House Without a Key. Headed here for a honeymoon, anniversary or proposal? Indulge in a dinner at La Mer, Hawaii's longest AAA Five Diamond-rated fine-dining restaurant.
