When it comes to the shuttle bus to the airport, it's better to think that you need to call the hotel. There is a list of hotels at Port B of the airport, and it is written to make a phone call, but it is not noticeable at all.
As for me, when I called, they asked which terminal I was and which air line I took , and told me to wait at sign one three. Before long the bus with the hotel name came.
This was my most concern about the hotel. Please share for your information.
