What is the best way to get from Pudong Airport to Crowne Plaza, Century Park, Shanghai?

Two methods are suggested for you.
The first one is the cheapest one. You can take the local subway line 2 to get to Science & Technology Museum Station. Then you can get out of the station from Exit 3 and walk along Yingchun Road to your hotel.
The second is the fastest and the comfortable one. You can take the maglev to Longyang Road Station and take a taxi to your hotel directly. From Longyang Road to your hotel, there is about 5km and the taxi fare is not very high.
