Hi, you can take airport A21 and get off at Middle Road, Nathan Road Station. You will find the hotel when you get off the bus. The cost is 33HKD per person. Imperial Hotel is just above the MTR station of Tsim Sha Tsui. You can take MTR for one stop to Admiralty and then take bus 629 from Admiralty Exit B2 to Ocean Park directly. The costs is 18.6HKD in total. A cheaper way is to walk from Imperial hotel to New World Center bus stop. There is bus 973. Get on this bus and get off at Ocean Park Road, Wong Chuk Hang Road. Then walk for a short while to the main entrance. The bus fare is 13.6HKD. The first way is faster. You can just walk from the hotel to 1881 Heritage Platform. Cross the Nanthan Road and turn into Middle Road till the end. Then it is the heritage platform.
