I stayed a couple of nights in Aguas Calientes and enjoyed the time. Arrived around 4pm and had a nice dinner. Machu Picchu next afternoon so had a lesiurely morning. then relaxed after MP and left the next morning. Did a hike to the museum. Walked around town and saw the statues. Dropped in the church. Found the library. Sat by the river for a while. Browsed in a few shops but didn't buy anything. Had several amazingly good meals in town. I was surprised at the quality of restaurants that were there. Of course, there are plenty of cheap or fast places, but I had a couple of really good meals.
