Hi, sorry if this question is silly but I want to be sure I am interpreting the Flexpreis ticket correctly: If I buy a flexpreis ticket for an ICE train on a specific date, does that mean I could take an earlier or later ICE train that same day without paying an extra fee? And is there any savings/benefit to buying the flexpreis ticket ahead of time, versus at the train station?
I want to take an ICE from Stuttgart hbf to Frankfurt Hbf to minimize train time on 17 April. My husband and I are visiting the Mercedes Benz museum, then dropping a rental car off at the stufftgart hbf. I’d like flexibility in train times in case we get done early or need extra time. Thanks!
