Frankfurt am Main for first-timers

The Eurial Global Flexible Pass has been easy to use and manage my tickets. It's nice that you can use one day and take multiple trains within that day (very helpful when you have missed your prior train). It provides most of the platform numbers at each station. Only thing I can say that I wish was better about it is that, it would be nice if there was a better list of train station names for cities (got on train to another part of the city)
