Hey!! I actually did a tour to China with a company called Intrepid last year, and it was absolutely AMAZING!! It’s great because they take care of all the planning for you, so you just sit back and enjoy. They’ll make sure you hit all the big stuff (Great Wall, Terra Cotta Warriors, etc.), but also do a lot of off-the-beaten path stuff, so you’re not just being a complete tourist, but a traveler!! Their itineraries go pretty much anywhere in China, so you have a number of choices!
Joran Beasley 805-968-5151 can help you with this-he just was on a trip with Intrepid Tours and loved it! Give him a call or email him at sba@statravel.com
Are you still planning a trip to China? I would love to help you out! I highly recommend going to the Southwestern part of China for some great sites and people. Let me know if you still have any questions!
