Options with traveling by train.

After considering my options concerning traveling by train, I think my best option would be to just buy the train tickets when I need them rather than buying the eurail pass. I am too old to purchase the Eurail youth pass (who would be in 2nd class). I could only get the adult pass, which if I got the adult global flexi pass, would be over $750 (and would be in first class). Everyone else that would be traveling with me from Franciscan would be in second class since they're under 26. I could sit in second class if I wanted to with the adult class. But why should I have to pay more for sitting in the same class as my classmates? I definitely wouldn't sit in first class all alone. So my best option would be to just buy the individual tickets (since you have to make a reservation anyway). This way I can travel throughout Europe and not go broke. Would I like to get the global pass? Sure. Do I have the money for it? No. I'm still trying to figure out how I'm going to pay for the trips to Poland and Lourdes. God willing I'll find some way to pay for it...even if it means working on campus all summer to pay for it.
