You can either take airprot express line to Hong Kong station, then walk to Central subway station through the underground tummel to take Hk subway island line to causeway bay, and then walk to parklane hotel. You may also take bus No. E11 to Yee Wo Street (Near Sugar Street) where is about 220m away from yout hotel. The former is fast but cost too much and you have to make a transit on the way. The latter is diret and cost only HKD21, but takes a long time.
