I need to get from the airport (Pudong) to the Radisson Blu Pudong Hotel (Century Park) - best way?

You can take the Maglev train and get off at Longyang Road Station, then take subway line 2 to Century Park and walk to the hotel. Or take a taxi directly from Longyang Road to the hotel. Or you can directly take subway line 2 from the airport to the Century Park and then walk to the hotel.
