Hello, I will be visiting Brno next month with a friend. While we are in Brno, the World Hockey Championship is taking place in Vienna and we have tickets to the games on May 14th (Saturday). I was just wondering if there are daily trains on saturday that go from Brno to Vienna. Also, should we order our ickets in advance? Or would we be safe just buying them at the station just before the train leaves? Thank you, -devin.
