Next week I'll be in Shanghai for 9 days. While my spouse will be working, I'll be left to explore the city with a friend. I've researched all the usual sight-seeing and shopping spots. I'm looking forward to doing a bike tour or two. I'm planning to scour the local newspapers when I get there for special events (concerts, art galleries). But still, I'm afraid that 9 days is a long time to be a tourist in one city, even one as big as Shanghai, and that I'll run out of things to do.
(from the reviews I've read of the expo, I'm not looking forward to that. I may attend in the evening once or twice).
Any recommendations to getting deep into Shanghai is appreciated.
