I was so ready to take on this adventure but unfortunately, the altitude was too much for me and I had to come back down.
Marco, one of the guides, walked me back and got me to a bus. On the their last day, I was able to meet with the group at the Sun Gate and join them for the guided tour of Macchu Picchu.
The guides, Rony and Marco, have been very helpful in communicating with me while I was recuperating, making sure that I get my ticket and able to join them at the final destination. All in all I was impressed by their skill and professionalism.
