Shanghai to Wuxi (Three Kingdoms City)

I will be in Shanghai and stay in Ibis Hotel near Chengshan Road Pudong. I would like to go to Three Kingdoms City (TKC) in Wuxi by train from Shanghai. Which is the nearest train station should I stop in wuxi? Is the TKC just a walking distance from the train station? or should I take a bus or taxi? I would appreciate if you could advise me. Thank you.
