As above, I've got a 4 day pass for July, and I have a question for the megaminds here, if they know.
We love Antwerp, Belgium, and are doing a one day over back in the middle of July, so using our in and out of the country days first, leaving 2 days after.
Then we're flying to Germany a few weeks later, and plan to use the other 2 days to go from Frankfurt to Berlin 1st class. We can still do this, right? The in and out of the country days don't end the validity of the remaining days, right? I hope so, and I assume so, but I'm am having a wibble in case it isn't so and I find this out from a german rail conductor who I can't argue with.
