Hi, We are arriving from MUSCAT. And would like to take the ferry from HKIA.

How far is the ferry jetty from HKIA?
Will we be able to pick up the ticket from HKIA for the transportation to the ferry jetty and for the ferry?
What will be the approximate cost?
How many hours will it take to reach Guanzhou from HKIA?
What are the ferry departure times from HKG
