What is the estimated travel time of bus from HKIA to Shenzhen(Metropark Hotel area)?

Hey, the bus takes about 2 hours to reach. And I found in the official website of HK airport that the first bus runs at 06:50 (not 06:20). However, the first bus runs to SZ North Railway Station, which is too far from your destination. So you're suggested to take the bus runs at 07:00 to nearby hotels (such as Century Plaza hotel or Shangri-la Hotel). After arrival, you can take a taxi to reach your destination very easily. I am sure you can catch your meeting AT 10:00. Take it easy!

For the first ferry from HKIA to Shekou Port runs at 09:00, it is too late for you.
