How can i get from Baiyun airport (guangzhou international airport) to Asia International Hotel?

Take airport shuttle bus line 2A and get off at the terminus station at Crown Plaza GZ City Center. After getting off, you can walk along East Huanshi Road to walk to your destination.

By the way, I'd tell you that the closest metro station from your hotel is Xiaobei station of line 5, but it requires several transfers from airport.
