I asked this question last week but didn’t get any useful responses.

I bought a 5-day pass for a trip and I am wondering if I should use a 4 instead, especially since I cashed my itinerary.

June 16: Train to and from Auschwitz and krakow. Night train to prague

June 20: Train from Prague to Vienna.

June 22: train from Vienna to Munich 

June 25: night train from Munich to Paris.

I should be fine with only 4 correct?
