Kei and I went to China with her two sisters and had a wonderful time. Smartours were quite complete and provided wonderful guides, hotels and more. The only complaint I had was the requirement that the carry-on had to be no more than 8"x10"x18" as 'required by China'. That was NOT the case and caused me some grief. That said I would certainly use Smartours again. As for me, Kei, the tour was as good or maybe better then I anticipated. Our primary tour guide, Oscar, was very considerate of all our needs, very patient, making sure we understood the protocols and behaviors of the country, as well as well versed in the histories of areas visited. The local guides were equally informative, and I found the Shanghai/Souzhou guide, Claire, very charming. I was happy to be able to keep up with the pace although I don't recall in the pre-trip information any mention of the distances we might be walking on often uneven surfaces. Maybe I missed it. All in all I grade the trip an A, for information, weather, travel arrangements, accommodations, meals.
