Is it a good idea to get Chinese currency before coming to shanghai and what is the easiest way to get to hotel from airport?

Hi, you can surely get Chinese currency in advance, but it is very easy to exchange upon yout arrival. As I know, there are several banks in the airport for money exchange.

The transportation is very convenient, by bus, MTR or Maglev. However, would you mind telling me the name of your hotel? Then I can give you more specific directions.
