Does the aiport express free bus shuttle service goes to METROPARK HOTEL MONGKOK or somehwere nearby

I'm afraid there is no free bus to your hotel directly. Anyway, after takeing Express Train and getting off at Kowloon Station, you can take free bus line K5 to the City View. Upon arrival there, you can take a taxi to your hotel within a few minutes. Or walk to Yau Ma Tei MTR Station to take Tsuen Line Line to Prince Edward Station and then walk to your hotel.
