The bahn website is confusing to me. If I buy this card, I can take any route to anywhere within Germany right? Is it limited to certain types of trains? I'm just travelling for a few weeks. I don't need to buy the Bahn 25 for 60 euro. I can buy the bahn-probe for 25? Moreover, how much do you think I should be travelling to make it worth it? I think I am spending atleast 200 euro on train travelling based on the savings fare, not deducting the bahn's savings. Another question is is it a good idea to book the train ahead of time? I'll try my best to be there on time, but there are always unknown factors. What if I miss my train but I already bought the ticket for a specific time?
