After reading the FAQ section here, I noticed there wasn't a link to a thread with this title.

We will be traveling in Jan on MU - JFK-PVG-BKK..BKK-PVG-JFK
On our way back through PVG, instead of a 5 hour layover on 1/10, we decided to make a 29 hour layover to experience a bit of Shanghai.
As a US passport holder, it appears that TWOV will be no problem and I'm assuming that MU wouldn't give me any hassles about the itinerary.

As Beijing and Guangzhou have an active thread on this topic, I wonder if i can get some assistance.
After doing some basic research, I know that my wife would like to see a top self acrobat show - Circus World looks like it might fit the bill - what experience have others had with these shows?

I am Diamond with Hilton and Gold with Marriott - which of these chains would be my best bet as far as location, upgrades and lounges go?

After spending 2 weeks in Thailand with the appropriate clothes for that climate, it looks like Shanghai will generally be in the 30's and 40's that time of year - I'll have to put some thought into how to pack for that 1 day.

Any another suggestions for this thread would be appreciated.
