It really may not be wise to even try to go to Tibet. This was my first instinct. This could happen at any time and we could be already in China and flying to Tibet to be turned away on arrival and have all kinds of complications. Then trying to get 20 people out of there could be a mess. I was originally and am still very hesitant about Tibet. I was not particularly fond of Tibet as you know but could have made the trip better than what we experienced when we were there.

If we find either or both Nepal and Bhutan are interesting for a post tour that may be the most sensible thing to do without such a risk of complications.
