Well thank goodness the hotel we booked also will transfer us to and from/ the train station from Cuzco for $5 each way and I was aware of the bus ride to Machu Picchu...I guess you need to be in line early morning to beat the crowd. Train tickets weren't cheap but I bought them online in case they sold out on seats It would have been a bummer to travel all that way and not see it! I would not have taken the bus from Cuzco!
