Did you visit the Bund/Y. Garden and thought either was worthwhile? I think my hostel is near the Bund and I'd be walking. Not sure what else I'm doing in Shanghai yet.
It's impossible to say what would be worth it to someone else, but we enjoyed seeing The Bund both in the day and at night. If you are within walking distance, it wouldn't hurt to go check it out.
We walked there the night we arrived. It was late and we had an early morning the next day to get to Disney, but we still felt it was worth the walk. We probably spent 15 - 20 minutes there.
The morning we were leaving Shanghai, we went back to The Bund to see it in the light.
We actually skipped a Yuyuan Gardens tour to go to SDL, so I can't answer that one
