We are reaching HK central by Airport express. Is free shuttle available to reach our hotel?

Is your hotel located nearby the Central Metro Station?
If yes, there is no free airport express or shuttle bus that can take you to the Central Station. You can take bus no. E11 at Airport (Ground Transportation Centre), and get off at Jardine House, Connaught Road Central. After arriving, you can walk to the station.
Or could you tell me the name of your hotel?
So that I can suggest you the detailed route and bus number.
