How to reach HK ocean park from hotel harbour plaza metropolis by MTR

Firstly, I'd like to tell you that MTR cannot directly take you for this journey. Well, I suggest you walk from the hotel to Hung Hom MTR Station to take West Rail Line to East Tsim Sha Tsui Station, from which walk to Tsim Sha Tsui. At the station, take Tsuen Wan Line to Admiralty Station, near which you can easily find bus no. 629. It will take you to the park directly then.
