我都忘了 Trenitalia 是四個月前預售。
自己去看 人家 seat61 歐洲火車旅行專家怎麽說的

如果樓主行程相當固定而不是隨性，舉個例子，我看不到付五十元臨時買比付二十元提早買有什麽好處。
比如他說去米蘭和弗羅倫斯，他定酒店也是臨時決定去才訂嗎？ 如果他已規劃好那天去那個城市 為什麽不能在票開賣的時候就買下來？不明白。
如果是走到哪兒算哪兒，那是可以臨時起意想去的時候才買票走。但樓主顯然不是這種旅行方式，而且比較關注是否早買票會比較便宜。 他的重點是省錢 不是靈活性。

Long-distance trains, yes. For example, Rome to Florence, Milan to Venice. All seats on Frecciarossa, Frecciargento, Frecciabianca & InterCity trains are reserved, so they can in theory sell out. However, as there are so many trains each with hundreds of seats there are almost always places available on most trains even just before departure. So yes, there's usually no problem at all buying at the station on the day if you want. The issue is price. Trenitalia ditched the old 'one size fits all' approach to pricing in 2009 and introduced cheap advance-purchase fares whilst increasing the fully-flexible base price. So on the day of departure you'd pay the base fare, Rome-Florence €45, Rome-Venice €84, but if you book in advance you can buy a cheap economy or super-economy fare from as little as ?€19.90 Rome-Florence or €29.90 Rome-Venice, assuming you're OK with limited or no refunds or changes to travel plans. It's your call!
