I booked the 4d/3n trip with Inca Trail Reservation, I was pleased to see that our group was probably the smallest in the trail (5 people) accompanied by five porters, a cook, and our guide Juan.
The only times we met the porters were during the lunch and dinner breaks though, for the rest of the time we were with Juan alone. We had three meals a day that the cook prepared , all that were of an excellent quality.
Juan made sure that no one ver exerts theme selves and would move with the slowest of us while allowing the rest to venture alone.
I would come back with them again.
