I would like to do a comprehensive tour of Nagaland and Arunachal Pradesh in December 2013. In my other thread I was recommended 29 days...but this sounds too long to me. Is Kaziranga National Park and Shillong worth visiting if I will see Tawang already. Also the ride from Bodmila to Kaziranga is a very long one I am told. How many days is good enough in this area of Nagaland and AP? Thanks.
