I plan to travel from Venice to Spiez via Milan. Then from Spiez I shall buy a half fare card so that I can use it when I buy the ticket from Spiez to Interlaken.
My question is whether is it necessary for me to buy the ticket from Venice to Spiez in advance or I can just buy the ticket in Venice train station when I reach Venice on 1.5.2013.
Is it possible that the ticket from Venice to Spiez sold out? I check Trenitalia and it shows that train from Venice to Milan is €29 and ticket from Milan to Spiez is N.A. What does that means? Is it cheaper to buy the ticket from Venice to Milan now or the price will be the same on 1.5.2013?
