Hi! We (me and my two teenagers) are traveling to Germany in 6 weeks. and I have already asked a couple of questions about logistics. Thanks to everyone for all the help so far, and I hope you will help with one more question. I finally bought our train tickets from Augsburg to Amsterdam, and I have the DB app, so the tickets are there waiting for use. The other two short journeys we have to take are:
Traveling from the Munich airport to Ostbahnhof station late in the day (upon arrival in Germany). I know we need to take the S8, and there was a one day airport-city group ticket somebody recommended, and I'm wondering if I can purchase it ahead of time so it's on my phone. Do I do this on the DB site or with the Munich app? Will I need to specify a day and time? I really prefer having all my tickets on my phone and ready to go. Also, is that ticket valid for 24 hours or only until midnight, because I'm guessing we will be tired and not likely to use transportation until the next morning. If that's the case, is it still the best option? Finally, if I get the tickets on the Munich app, how do I validate them?
Two days later we will go from Ostbahnhof to Augsburg. Is it best to get a Bayern ticket? Are there multiple day Bayern tickets that would cover both the airport trip and the trip to Augsburg? Also, since the journey is short, I am guessing it's not worth buying first class right?
Thanks in advance for your help!!
