Hi everyone! My boyfriend and I are first time Interrailers and we bought a 7 days in 1 month Global Pass. Our journey will start next Friday, so we haven't activated our pass yet but are looking into that. We just don't really get how it works...we read that once you activate your Pass, you can't change your trip anymore. But what if our train time(s) change? We saw that you have to "swipe" your journey to get a ticket but we're just a bit confused and nervous about how it works exactly.
Help is very much appreciated!
