I have visited Park Island and liked it a lot. As a single guy working in Sheung Wan I still think its very suitable. Easy to get to and like others have said the expats are really pretty cool over there from what I've seen. Not at all like the boring type on DB who are mainly Americans, the Park Island xpats are more mixed. Beach side cafes and bars seem OK. The facilities are the 5-star hotel quality. Very nice pools and outdoor areas. And you will get way better size of apartments and high quality furnishings there. They have property agents by the bus terminal and also by the ma wan village. Overall very good value and very visible. Did not notice any humidity. As for airport connections, most times when you fly or land it will be between 6am and midnight, so using the airport bus is ideal. If not use the taxi. Also as others have said, it is kind of an island but is now fully connected to the highway so fine for car access to park island if needed for taxi, ambulance, delivery vehicles etc.
