Advice for Shanghai/Ningbo

This will be my first trip to trip to this area and need some expert advice. I’ll be flying into Shanghai and attending a show at the Shanghai New International Expo Center. I’ll have a full schedule so I’m looking for advice for hotels that will be easily accessible to the expo center, and hopefully also close to some good mongering areas. Any ideas/suggestions?

I will also have the choice of spending the weekend in Shanghai before traveling to Ningbo, or the reverse. How is the scene in Ningbo? Should I stay in Shanghai or venture to new territory for the weekend?

Comfortable spending -$130-$170 if needed.

I'd stick with Shanghai as there is so much to do and see. There is some phenomenal talent avail at the ST BBS's for real cheap (approx $20). Hit up some of the numerous sexy saunas, where they still do the "red rope" treatments. Lots of "legit" saunas all over. All this info should be in the Shanghai section. If it's you're first trip, consider staying in the Pudong area, plenty of nice hotels around there.
