how do i get to baigong hotel from baiyun airport?how much it cost and how many time to get there?

Upon landing, you are suggested to take subway line 3 at the airport, and get off at Yantang Station. Then transfer to subway line 6 to Cultural Park Station, Exit A. It takes around 50 minutes on the way. And the ticket fare is CNY 8 per adult.
After arriving, walk to your hotel directly.
