Can I use free shuttle service from Hong Kong International Airport to Holiday Inn Golden Mile

Well, this free shuttle service is only provided for Airport Express (AE) passengers. And passengers are required to show proof of eligibility including AE train ticket, Airline ticket or boarding pass. So you cannot enjoy this policy.

Upon landing, you can take bus no.A21 at Airport (Ground Transportation Centre), and get off at Middle Road, Nathan Road. Then walk to the north around 220 yards to get there. It takes around 70 minutes on the way. And the fare is 33 HKD per adult.
