Our trip in December will be better suited if we get a "D" ticket for Munich and Salzburg. I know it gives us a lot of choices to take any local train. I am also aware that I cannot buy the ticket until 5 days before the beginning of the month of use.
For a longer trip such as from Munich to Salzburg, if we wanted to reserve seats, would we be able to do so? I know this entails identifying a certain train and we must take that train to utilize reserved seating .
Since I cannot buy the "D" ticket until the end of November, nonetheless, would I be able to reserve seats on a specific train even without having purchased a ticket yet? About a month out, I would like to reserve seats together for the four of us traveling together.
