How to get from Shenzhen Airport to Harbour Plaza Hong Kong?

First, out of Shenzhen airport, I found the bus at Luohu outside the airport and got on the bus.

When we arrive at Luohu, we will go through the customs. After going through the customs, you will see the Kowloon-Canton Railway, and then take a bus. I don't know where the hotel you mentioned is. . . . Ask others when you get there, usually under Tsim Sha Tsui or Kowloon Tangxia. Just change to the subway after getting off.
