As I have previously mentioned, our family was quarantined in China. We did not get quarantined right off the plane, but had started the tour and were removed from the China World Hotel. We flew from Chicago to Beijing. No one in our family had a fever or any H1N1 symptoms. We were quarantined because someone on our plane had either symptoms or the actual flu (not sure) and we were sitting within three rows of that passenger.
If you are quarantined you get to stay together as a family. You get to take all of your luggage. We had Internet access. You must stay in quarantine for seven days after your flight lands in Beijing.
I highly recommend you look into Skype because that is how we stayed in contact with our family back home.
Quarantine is a very real threat. It is a very unpleasant experience. There is nothing the U.S. Embassy can do to assist you. You have to follow China's rules.
ABD was FANTASTIC throughout the entire experience.
I am sending you all good wishes to avoid quarantine. I'll be glad to try to answer other questions you may have.
I hope you get Brian and Daisy as your guides. They are wonderful. Have a great time and enjoy China!!!!!
