We plan to be in the Shanghai area for 9 days in June. To my astonishment, most posts I have read said you don't need more than 3 days to see Shanghai. Given that this is true, we are thinking of going out to Hungzhou, and Ningbo to round out the other days. Is this is sound plan and better yet, are there other places near by which we should consider? Our family of 4 includes 2 teens. And our current plan is to stay at the Hyatt on the Bund for 1st 2 days and P Hyatt on the last day before departure. Any help will be appreciated!
