Family of 4 (2 adults, a 14 year old and an 11 year old) will be taking the train likely about 2, possibly 3 days throughout Germany and then into Austria (additional 2 days). Is the Eurorail pass the best way to go? We will do a mix of car rental and train due to visiting family members who would not be able to fit us in their cars to go out to dinner or do activities that are not convenient to the train. If yes to Eurorail pass, is 1st class something we need to be sure to get seats?
Likely routes for Train, all on separate days:
-Train from Frankfurt to Hof after we deplane (then rent car in Hof)
-Train from Erlangen (staying there near family) to Nurnberg for a day trip (doesn't seem to be worth it to use eurorail pass for this as it's a 15 min ride and we could just buy inexpensive tix or no?)
-Train from Erlangen to Bamberg for another day trip (again, doesn't seem to be worth it to use eurorail pass for this as it's a 15 min ride and we could just buy inexpensive tix- or no?)
-Dropping car in Biberach and then take train from Biberach to Salzburg
-Train from Salzburg to Vienna
My cousin will drive us to the airport in Vienna from our hotel so no more train after that trip from Salzburg to Vienna.
Thank you, as always for your help!
