I will be heading to Italy in the next few days (I'm currently in the middle of my two month backpacking trip) and have heard that travel between Italian cities on the trains can be very confusing. I am using a Global Youth Railpass (already validated) and I heard all train tickets must be validated (again I assume, or the conductor gets angry), but do I still have to do this on my Global Pass? No other conductor has ever stamped or punched it on other trains I have taken...
Also, is it true that getting trains to different cities within Italy is more difficult? I haven't had a hard time in the other 7 countries I've visited but have heard it can be... I just want to be well-prepared.
Thanks! :)
