Thank you for the response you gave for my earlier query.

I would like to know whether there are budget hotels, inns, motels within short distance to the Pudong intl aiport. if so can I please have the names or a link so I can check them out.

Also I want to know the ticket price for the train journey from shanghai to beijing. Do I have to book the train in advance?
And also I would be grateful if you can give me some hotels in beijing close to the great wall.
Thank you.
