we are visiting hongkong on june 27-30 we will be at L'nina hotel. how can we get there in ocean park

Is it L'hotel Nina et Convention Centre exactly? If so, you can take bus no. 629 to travel from the park to Admiralty Station, where transfer to subway Tsuen Wan line to Mei Foo. At this station, transfer to West Rail Line to get off at Tsuen Wan West Station, which is within 3-5min walking distance from your hotel then.
