How can I get from regal Shanghai east Asia hotel near stadium to Zhujiajiao water town?

Yes, you can take a taxi and the fare is about CNY170.

You can also walk south 400m to take Metro Line 11 to Jiaotong University and transfer to Metro Line 10 to Hongqiao Railway Station. Then transfer to Metro Line 17 to Zhujiajiao. Get out of the Exit 1 and walk north about 1.5km to the town. It takes about 2 hours and costs CNY7.
