Is there a free shuttle bus that can take u directly to langham tsim tsa tsui, hong kong?

I'm afraid there is no such a direct free bus to your hotel if you are departing from HKIA. Well then, I suggest you take Airport Express to Kowloon station first and then transfer to free shuttle bus line K3 to get off at Hyatt Regency Hong Kong, Tsim Sha Tsui. Then you can walk to your hotel in several minutes!
