We want to travel from the Netherlands to Rome, however, the tickets are very high in price when we book a retour ticket which includes the Nightjet from Munich to Rome.
I am looking at this option: Booking a Global pass (4 days in 1 month) and booking the OBB nightjet with discount for the interrail pass… it safes me a lot of money.
Now I wonder, do I forget something? Can I use the Interrail pas for traveling from the Netherlands to Munich? And then discount on the OBB Nightjet.
Or do I need extra tickets as well, which makes this plan a lot of money as well?
if you book early enough you could get for just 40€ from Munich to Rome :) 
and then find the train already aold out :/
