One of the Aqua chain’s most expensive—and nicest—hotels is the Lotus, on the east end of Waikiki, facing Kapiolani Park. It’s a former W Hotel property, newly updated with dark hardwood floors, platform beds, granite-tiled bathrooms, and—in the corner units—a lanai and window that frame Diamond Head beautifully. You can sleep with the windows open here; this is the quiet side of Waikiki.
