I'm a little unclear about train reservations, especially from outside Peru.
(We don't speak Spanish if this make a big difference)
We (2 of us) are arriving in Cusco via bus from Lima ~11am in the middle of November (week day). We would like to have lunch and bus to Olly and then doing some tourist things there and then catch the late afternoon/evening train to Agua.
For those who are experienced, do we really need to book way in advance? We would lose flexibility if we do that? Also, are there cheaper "local train/fare" that we can take if we just show up at the train station in Olly?
Similarly, we are leaving Agua 2 days later in the morning, so we don't have a deadline. Is pre-booking a train ticket out of Agua to Cusco/Olly required/recommended?Edited: 2:21 am, October 05, 2012
