2 more questions....

1. Co-worker wants to get guide (her sister used in the past) - fine, I know we could do on our own but I'm ok with a guide (not just a driver) because I love history and details. We had planned 1 day - Temple of Heaven & Summer Palace (to do Forbidden City on our remaining half day on our own). Co-worker now wants to do Great Wall as sister says we must and it's not that far. So - next week, is it crazy for us to do Temple of Heaven in the morning and then the Great Wall (geez, I haven't even checked to see which section is the closest/most common from Beijing - Mutianyu?) in the afternoon? (or vice versa if the guide recommends - he's quite opinionated ;-)

2. Dinner on Sunday, our flight lands at 16:00, we'll have major jet lag but co-worker wants to go out to dinner. Recommendations near National Library subway? Feasible to take a taxi to Drum Tower area for dinner and not be out too late?

Thanks!!
