How I can go east Nanjing road from Pudong intl Airport? I reserved hotel in there.

There are three ways to get to Nanjing Road from PVG airport. The most economical way is to take east extention of subway line 2 to Guanglan Road, change to subway line 2 and get off at People's Square, then walk to the destination. The fastest way is to take meglev train to Longyang Road, and then transfer to subway line 2 to the destination. The taxi fare from airport to Nanjing Road is around CNY150-200. As for the tickets, do you mean the high speed train between Shanghai and Suzhou? There are many trains between these two cities, so it is quite easy for you to purchase the tickets on the spot or book it in advance.
