We have some family members living in the area who have offered to pick-up our tickets before we arrive. Does anyone know if the ticket agent will require passport numbers or any other information on us beyond our names? I want to make sure we're providing our family with all of the necessary information.
The other option is for us to buy our own tickets when we arrive (which is only two days before we depart by train) -- is that cutting it too close? Do these trains sell-out or sky-rocket in price?
