When I try to book a train ticket through Trenitalia website there is an option for Smart & Smart 2. Is anyone entitled for those discounted prices?
After I submitted my information in the “TICKET DELIVERY” section it read…
“Self Service (Not present in the departure station)”, and the home delivery option was available but wouldn’t take my USA address. Both ticketless options were unavailable to me as well, because the were grayed out.
Is there anyway I can get this ticket at the discounted price?

Train: Euronight 485 date: 24/09/2010 from Muenchen Hbf (21:03) to Venezia S.
