question for you: will you be returning to Beijing anytime soon?
The reason why I ask, and I know some people will disagree, is that I think you should hit the "tourist" stuff if this is a first/last for a long time/maybe never again trip. If a person is going back/forth then there is time for the nuanced trips to better areas of the Great Wall, not making ANOTHER trip to the Silk Market or skipping on the Summer Palace. However, I think some of us experienced China travelers often unfairly spit on the plans of excited first timers.
So I say do all the cheesy crap and have fun. So I can give you my take...
* what time are you scheduled to land at PEK on Friday - overseas flight or intra-China flight?
* Where/in what part of town are you staying?
* How many people?
* Do you speak Mandarin?
