I had a great time on this trek. The tour guides were knowledgeable and encouraging, and the trek well planned.
I can't say enough about the porters as they made life much easier. They woke us up first thing in the morning with coca tea in the tent and soon after we had a full breakfast waiting for us in the common tent.
All throughout the day we were treated with great food and helpful guides. They even had a "happy hour" prior to dinner, and although non alcoholic, it was a good time.
Highly recommend using Inca Trail Reservations if you want to see Machupicchu.
