Having had not much luck with the administration/office side of SAS Travel in booking the 4day/3night Inca Trail, I was a little worried that I would be disappointed in the trip. However, the SAS guides who led my group were incredible. Knowledgeable, helpful, friendly, interactive they provided loads of information on the trail and could answer questions on just about everything. It was a serious treat. From warm water in bowls in the morning for washing, to delicious coca tea, amazing food for breakfast, lunch and dinner the whole experience was fantastic. If you manage to get on a trip with Herlin, Valentine or Hilbert leading your tour you are in for a treat.
