Is it better to go to Shanghai Happy Valley from Nanjing with a group or by yourself?

Of course, it is still cost-effective to join the delegation in Nanjing. I study in Nanjing. People are in Shanghai, and the railway station is far from Happy Valley. It's best to go directly by car. Besides, it's definitely cheap for a hotel to join a group. If relatives and friends are not far from Happy Valley, they can play by themselves. The D-prefix train has a first-class seat 1 10 and a second-class seat of 93 yuan. It is not recommended to take a taxi to the railway station.
