We are a couple that lands 13.05 6th of November and on transit to Bangkok.

Hi,
We would like to use the 72 hour visa to visit the Wall and the Forbidden city among other attractions.
Is the wall inside Beijing administrative zone?
What is the best way to arranged this together with hotel nights close to the airport ? We do not want a private tour due to high costs and budget restrictions.

When is the latest that we have to depart for Bangkok? End of 9th or 13.05 the 9th of November?

We are also coming back this route, will that count for a second free period?
