A follow up question or planning. I am trying to figure out all of the places that we will need to go through customs. I know we will after we land in Venice from the US. I assume that we don't have to worry about customs on the train from Venice to Munich. I also know that we will clear customs in Dublin prior to flying back to US. Making sure my assumption is correct about the train. But really wanting to know what to expect on the flight from Munich to Dublin.
