approximate fare for a taxi ride to Shanghai Pudong Airport from Holiday Inn Express Wujiaochang?

Does anyone know:

1. approximate fare for a taxi ride to Pudong Airport in Shanghai from Holiday Inn Express Wujiaochang 1729 Huang Xing Road?
2. how long will the cab ride take?
3. do you get charge extra for luggage / extra passengers?
4. is it better to agree on a set fare to the airport rather than meter?

Thanks
