I want to take the subway from the Baiyun Airport to China Marriot Hotel which is near Yuexiu Park Station (越秀公园). I know I have to make a station transfer at Jiahewanggang (嘉禾望岗)to get from Line 3 to Line 2. Is it a long walk at the from Line 3 to Line 2? I have heavy luggages so I am worried that it might be a long walk to transfer from Line 3 to Line 2 at the Jiahewanggang Station.
