I'm heading to Switzerland in early September, and will be taking a short trip down to Venice while there. I've already figured out all of my Swisspass details, but I'm really confused on how to get from Bern to Venice. I know my pass will get me from Bern to the border, and then I need a point to point to Venice, and for the return trip. I just can't figure out how to buy that point to point.
I've tried using the German rail site, but I just can't figure it out, or at least enough to figure out this specific question.
I've also been advised not to buy this ticket until I land in Switzerland, no need to buy it in advance. This is my first trip to Europe, and I'm the typical nervous newbie traveler, and would prefer to buy in advance if I can.
Can any of the much more experienced travelers offer up some advice? Maybe just assuage my concerns about waiting until I'm there? I'm sure I'm being overly tense about it.
