Hi Mr. Ng, I think this is the best way for you. It takes about 70 - 80 minutes and costs anout CNY 20. At Pudong Airport, take the Aiport Shuttle Bus Line 3 and get off at Longyang Road Station, and then take the subway Line 2 to the People's Square which is very near your hotel. you can just walk to the Ramada Plaza Hotel in two minutes.
Or if you want to take a taxi from the airport to the hotel, it costs about CNY 150 and takes about 50 minutes.
