Hi! My family is going to hongkong for the 1st time. We will be arriving at hk airport around midnite. Is the bus A21 already available in the airport to take us to Shamrock Hotel? We are also planning to go to HK disneyland on our 1st day. How to get there by mtr? Then our flight going back to the Philippines is around 3am, what bus number can we ride going to Hk airport? Your response is greatly appreciated. Thanks.
