I am planning to go to Nanjing to study abroad. I wanted to fly into Shanghai and then take a train to Nanjing.
Question one: Which Shanghai airport should I fly into if I want to get on this train that will take me to Nanjing? Question Two: Is there a shuttle that will take me to the train station to catch the "to-Nanjing" train?
Question Three: Which train Shanghai train station is it? Shanghai Railway Station or Shanghai South Station? Question Four: Where, in Nanjing, will the Shanghai train drop me off at?
Question Five: Where can I get an up to date schedule of the trains leaving from Shanghai to Nanjing and their prices? How often is it changed?
Question Six: Do I pay for it when I get there or can I pay for it before I get on the airplane to Shanghai? If so, will the ticket be sent to me in the U.S. or do I have to pick it up (and where)?
Question Seven: How much in advance can I buy/reserve my ticket?
