Planning a trip for 2 weeks in Germany & Austria mid-July. We plan to take trains the entire way and I'm confused by the options. The regional Bayern ticket seems great, but not sure if it matters how far we travel (do we buy the Bayern or purchase one way fares to that specific city)? The Bayern time restrictions are no problem. First part of the trip (thru Day 6) there are 2 adults traveling and on Day 6 we add a third adult traveler for the remainder of the trip.
Train travel itinerary: Day 1: Frankfurt Airport to Trechtingshausen, Day 3: Trechtingshausen to Rothenburg ob der Tauber, Day 5: Rothenburg ob der Tauber to Freising (MUC Airport); Day 6: Freising to Salzburg, Day 9: Salzburg to Innsbruck, Day 11: Innsbruck to Munich.
There doesn't appear to be any advantage to purchasing tickets in advance - is that correct? Must the Bayern be purchased for a specific train/time? Or once purchased, can it be used on any train travel for that day?
I appreciate any assistance!
