What is the best way to get from Dorsett Tsuen Wan Hotel in hong kong to the cruise ship terminal?

Do you refer to Kai Tak Cruise Terminal?
If yes, take Tsuen Wan Line at Tai Wo Hau Station, get off at Prince Edward Station. Then transfer to Kwun Tong Line to Kowloon Bay Station, Exit A and bus no.86 to the destination. The whole way takes around 70 mins. It costs 15.3 HKD per person.
