i just returned a few weeks ago from my first trip to Peru which I did with a friend in only 8 days. We were on a small gropu tour with Adventure Life and had a GREAT time. We had added in some cooking classes/foodie stuff along the way which made it even more interesting for us since I don't care much for ruins touring. my favorite part was the sacred Valley which is gorgeous. I hear that some people skip over this part and just do cusco and Machu pichu, but i think that would have been an oversight. this was the least touristy part about the whole trip and my favorite. my only regret is not taking more time in each place.
