Underground travel in hong kong

By saying Underground travel, I presume you wanna experience the MTR way. Well, it is not a direct line. U need take Airport Express train to Tsing Yi and then transfer to Tung Chung line to get off at Tung Chung. Then you can easily walk the hotel. In addition, bus is a better way. Shuttle bus no. S1 can take you directly from the airport to Tung Chung bus terminal, which is only several minutes' walking distance to the hotel.
