Hi. We are arriving in Hong Kong on August 8 (9:30 pm) and will be staying at the Nathan Hotel. Can you give us the number of the airport bus that we should take? We're saving on tranport costs and do not want to take the airport express. Are the airport buses available 24 hours? If not, what time is the last trip? Lastly, how long is the estimated travel time from the airport to the Nathan hotel? Thanks in advance.
