I will be staying in Ramada Plaza Guangzhou from 22nd - 27th Dec 2012

You can take subway to get to those places. When go to Tianzi Wharf, you can walk to the East Railway Station to take subway line 1 to Gongyuanqian and transfer to line 2 to Haizhu Square, then walk about several minutes to get there. Well, the One Link Plaza is just nearby Haizhu Square. Going to Zhanxi Road, you can take subway line 2 to the Railway Station, then walk there. Going to Beijing Road, you can get off subway line 2 at Gongyuanqian, then walk there. Well, going to Xingangxi Road, you can take subway line 3 from the East Train Station to Kecun and transfer to subway line 8 to Zhongda Station. Get out of the station, you will be at Xinggangxi Road.
