I book through Adventure Center (www.adventurecenter.com) in Emeryville; they have info on about every out of the way place and basic tours.You can Email: and she should be able to help you. Really nice and knowledgeable person. I don't know if they do independent travel, but if not, maybe they can direct you to another source. Also I don't know how high on the food chain you travel. And if you have definite January dates.

Good luck with your plans! Cheers! Jo, still in Sunnyvale, but leaving before Christmas!
