Whilst not everybody would rate the W a true luxury hotel, I would take the fast train 1 stop further and stay at brillant Four Seasons (same building complex as train station). Don't forget to dinner at the first 3 Michelin Star Chinese Restaurant worldwide, Lung King Heen - and don't forget to swim at their fantastic pool on top of Hong Kong Harbour! For room choice, every room from floor 10 upwards is fine there...
