how do I get to star ferry from East hotel in Tai koo, hong kong?

I wonder whether you refer to the star ferry at Tsim Sha Tsui. If so, here is my suggestion:
By mtr: walk to Tai Koo mtr station to take Island line to Admiralty station, where transfer to Tsuen Wan line to get off at Tsim Sha Tsui. Get out from exit F to walk there.

By bus: walk to Cityplaza, Taikoo Shing Road bus stop to take bus no. 110 to get off at Peking Road, Canton Road. Then you can easily walk to the star ferry.
