Hi, I have a 11 hour stopover in Guaghzhou. Will I be able to travel to Hong Kong and the City of Guangzhou without a visa? I have a US passport. I hate to wait in the airport for 11 hours. Is there a bus tour available for transit passengers?

Is there a place at the Baiyun airport that I can use to take showers and clean up?

I will be travelling on October 28.

Thanks
