I've been reading over the FAQ page and terms on eurail.com before I purchase my pass (first trip to Europe, so I'm trying to triple-check everything) but there are a couple points that I don't find as clear as they could be, so I could use some clarification on how these passes actually work. There may be more than 1 specific question below, but I believe they are fairly related.
I planned on getting the "10 day within 2 months" pass between France and Germany. From what I can tell, that means I'm able to choose 10 non-consecutive days within that period, correct? (example, could I travel every day from the 1st to 9th, then use my last day on the 25th?)
Related to the previous question, how do trains spanning more than 1 day count? I was planning for at least one of my trains to span a night (ex. Lyon to Munich). Do both days count toward my total 10 if I were to leave Lyon around 9 and arrive in Munich around 12 and there are a few transfers throughout?
What determines the start date of my 2 months? I'm assuming I have to do something other than just getting the pass and my 2 months starting immediately. Do I have to activate it somehow? Does it begin when I start traveling?
