A flexible Interrail pass includes 2 days to leave/return to your origin country. All other trips must be taken in foreign countries.
How does this hold if one wants to cross their origin country?
For example:
- Starting from Germany, to the Netherlands
- Then, wishing to visit Poland
There aren't too many ways to get from the Netherlands to Poland by train that doesn't involve crossing Germany.
Considering that the travel would bring the traveller in Germany, I don't think it would be valid, but considering that the traveller is not going to Germany, but rather to Poland, it might?
Is there an authoritative source that specifically details this case?
