5. Go to Shanghai and book a hotel during1.

Economy hotels can be considered. Many hotels have launched Expo rooms. However, because of the Expo, during the Expo, all hotels canceled preferential rooms, and all room prices rose. You can choose the surrounding areas, as long as the traffic is convenient, such as near the subway, or near the railway station and south station, instead of choosing the Expo site. I recommend Hanting and Home Inn to you, but it's almost more than 200. You can check them in official website. You can choose Pudong, Xuhui, Luwan and other surrounding areas, and choose cheaper ones. Still have to hurry, maybe there will be no room then.
