Last time I've splitted my HKG stay between the Marriott SkyCity and the JW HK Island. As been mentioned before, Lantau Island offers some attractions too, and Tung Chung is great for shopping; also the departure point for the cable way to the Big Buddha. Got seaview club room at SkyCity , but well, it's not HK harbour, so not really makes a big difference.. airport view might probably be more attractive. Club lounge is quite huge and not bad, though the JW's of course better (don't know about the CY).
