Hi Pat, John, 
Thank you so much for your reply regarding National Parks & Canyons, it has helped me make up my mind, will book this trip for September within the next 7 dYS. 
Pat your trip to china will be amazing, you are correct it is full on, but so different, I enoyed every minute of the experience, you are so well looked after by the just you rep, you only have to do what you can copewith, but I know you will want to do and see everything, "great wall" "forbidden city" terrecotta army.  I just think how fortunate we are to have seen just a little of this world compared to some. 
Just enjoy which I know you will. 
Thank you Pat and John for your reply much appreciated.
