hongkong int. airport

coming from hongkong int. airport which bus # do we take to reach our hostel, May Leaf Guest House which I think is in Chungking Mansion Building and also we are booked to do the Lantau Island Tour and Hk Island Tour. Unfortunately May Leaf Guest House is not included with the tour's hotel pick up list. Some of the hotels are Holiday inn Golden mile,Novotel nathan road,Metro park hotel Langham Place, Kowloon hotel. which one is the closest to go for the tour pick up or any suggestion pls. Thanks.
