Yangzhou can play the Slim West Lake, Wenchang Pavilion, suggested a day trip, the morning to go to the Slim West Lake, and then go to the city center, that is, Wenchang Pavilion around. Have a dinner can go back to Zhenjiang.
From Zhenjiang to Shanghai by high-speed rail. The ticket price is more expensive more than 100 dollars. But really fast. Shanghai can play 2 days. The room price is more expensive! Live one day. You can go to the World Expo, the Oriental Pearl, Nanjing Road around.
If Zhenjiang's neighboring cities, you can also go to Nanjing, high-speed rail is also very fast, very close. You can go to Fuzimiao, Xinjiekou, the Presidential Palace, Zhongshan Mausoleum. Anyway, it depends on whether you want to go back to Zhenjiang to live at night. If you don't come back to stay, you can stay in Nanjing for 2 days and stay there for one night.
Zhenjiang two days can play down, the morning to Jinshan, and then go to Jiao Mountain, Xijin ancient ferry, Nanshan, Beigu Mountain. You can choose whatever you want.
The itinerary is as follows, Nanjing 2 days, Shanghai 2 days, Yangzhou 1 day, Zhenjiang 2 days. Before and after a **** 7 days. The order of your own arrangement.
If 7 days according to my so play. The budget is about 1500 bucks. Stay in budget hotels.
I hope the advice you are satisfied.
