I want to take a night train from Munich to Venezia.
It leaves at 23pm and arrives 8am next day, so I would need to take this one because of the way I’m managing my travel days.
However, when I try to purchase the seat reservation it shows me an information like in the picture below.
once I cannot buy the ticket, I was wondering if I could just take the train without seat reservation, once I have no other way to make this trip
