What airport bus number from Terminal 1 to Cosmo hotel and how much per pax

There is no direct bus from the airport to the hotel, and you have to transfer many times on public transportation.

You can take Airport Express Line from the airport to Hong Kong Station. Get out of B2 Exit and walk about 200m to take Bus Line E22A from Jardine House, Connaught Road Central to Admiralty Station, Queensway. After that, transfer to Bus Line 56A and get off Queen's Road East, outside Queen Elizabeth Stadium. Walk about 150m to reach the hotel. It takes about 1 hour and costs HKD 6 per person.
