I paddled in Western Sichuan province up to the Tibetan plateau with three other boaters led by Travis Winn in the Fall of 2004. It was set up through Shangri La River Expeditions (
http://www.shangri-la-river-expeditions.com/), which is run by Travis' dad Pete out of Grand Junction. Surf around their site and you can find a description of our trip, as well as several others.
Some thoughts:
If this "World Class Kayak Academy" is anything of the sort, you'll have translators. It would be damn near impossible to pull off that kind of trip without them. Learn some basics, like "thank you", "hello", "goodbye" and "one large beer, please" and you'll be fine. Carrying your passport and a hotel card while on walkabout is always a good idea.
The people were very friendly everywhere we went. Some of that probably had to do with our excellent guides, who were actually speaking Chinese with them, but I never felt like I was in a hostile environment. Just put your best foot forward and be friendly and respectful and you'll most likely get the same in return. I always felt safe, even if that was an illusion of my own making. You won't pay what the locals pay, but getting "ripped off" in China is still pretty cheap by US standards.
The food was fantastic in Sichuan, but pretty bland in Tibet. We had goose tongues and cows forhead stir fried in tasty Sichuan sauces our first lunch, and quit asking after that. Without knowing where you're going, your mileage may vary, but I say try it all, as that's part of the experience. So is getting sick for a few days. Just accept it as inevitable and count your blessings if you get lucky.
I believe there are some vaccination recommendations that you can get through Rose Medical Center, but it may be too late. Call Rose to find out if you haven't done it already.
Rivers range from pristine to foul--same with the air. As a general rule, the higher you go, the cleaner the water.
There are first descents galore available for the taking. As big as you want. Maybe bigger!
Good luck--
I expect you're in for quite an experience!
