Need to cover the bund, yu garden and Nanjing road from InterContinenal Shanghai NECC.

1. From your hotel to Nanjing Road: You may walk about 650 meters to East Xujing Station and take metro line 2 to East Nanjing Road Station, Exit 2. Afterwards, you may walk about 100 meters to the destination. The ticket fare is CNY5/person.
2. From your hotel to the Bund: You also need to take metro line 2 to East Nanjing Road Station, Exit 2 first. Then you may walk about 50 meters along Middle Henan Road and turn right for 100 meters to East Nanjing Road Middle Jiangxi Road Bus Stop. Then you can take the bus no.37 for 1 stop to East Zhongshan 1st Road East Nanjing Road Bus Stop. Upon arrival, you may walk about 500 meters ahead to the Bund. The ticket fare is CNY7/person in total.
3. From your hotel to Yu Garden: You may take metro line 2 to Hongqiao Railway Station and transfer metro line 10 to Yu Garden Station, Exit 3. After that, you may walk about 400 meters along Fuyou Road to the destination. The ticket fare is CNY5/person.
4. I am afraid that you cannot cover these places in one evening. Yu Garden is closed at 16:45, so you cannot visit there in the evening. However, you can visit the Bund and Nanjing Road in one evening, since they are quite close with each other.
