I have been to Shanghai many many times and have seen most if not all of the tourist sights, but I've never been to Shanghai alone. In fact, I've never been to China alone because I don't think it's a single-traveler-friendly country. Any recommendations on what to do for an old timer going to visit Shanghai alone for the first time?

I am fluent in English and Mandarin. I will be staying at the FS Pudong, or Le Meridien (most likely the FS).
