We are planning on visiting the Summer Palace before our 12:4pm flight, so we figure we need to leave around 10:30am to get to PEK by 11:30. So we want an early start.

I read that the complex opens at 6:30am but the "scenic spots" open at 8:30am. But I can't figure out what the scenic spots are? What would we be able to do/see between 6:30am and 8:30am?
