So as you may or may not know, a lot of people who go to Machu Picchu actually skip Lima (which is a shame cause it is a cool city) and go straight to Cuzco and then to Machu Picchu.
However is Cusco is one of the highest cities in the world and Elevation Sickness is common. Common enough that when we call the DR to tell him where we were going they gave us a Typhoid Shot, Hep A Shot, Antibiotics for Tummy Trouble, AND elevation sickness meds, standard.
We decided to skip Cusco and go straight to Aguas Calientes, (which is truly the starting point to get to Machu Picchu), for two reasons, to hopefully avoid any sickness, and second after the 1 1/2 hr plane ride to Cusco you still have to take a train to Aguas Caliente, which is usually another 3hr train trip, and then from THERE you take a 30 minute bus ride up the mountains on a one lane high way to Machu Picchu. So that means if you start from Cusco you have 2 to 3 1/2 hours of travel before your climb even begins.
So of course we find out that the Train Station in Cusco is closed for repairs, so we need to get to the train station in Ollantaytambo which is 1 1/2 hours outside of Cusco. We decided to get a driver from KB Tambo tours and sight see on our way to Aguas Calientes because or our flight came in at 12.40 pm but the only train ticket we could get left at 7pm that night.
Then we would have an additional 1 1/2 train ride in the dark to get to Agqua Calientes, where we would check in eat and go to bed to get ready for Machu Picchu the next day.
