Actually, it is not suggested that you take the Maglev, which will make your journey to the airport complicated. From Wuxi, you could take an express train to arrive in Shanghai Railway Station around one hour. Just at the south square, the shuttle bus Line 5 could be taken to the Pudong Airport.

Of course, you could take the subway Line 1 firstly and then transfer to Line 2 at the People's Square. The Line 2 could take you to Longyang Lu directly.
