Well, March 10th is the end of regular season, but there are always the playoffs. Quarterfinals start on March 20th and with Munich, Augsburg, Straubing and Nuremberg (Ice Tigers), you chance of at least one Bavarian Team within your reach making it there are pratically 100%. Even the chances of one of them nabbing Berlin for an opponent are pretty good. With hockey rarely ever being sold out in Germany, I`d just check it out a couple days before and go for it.
If the NHL has started up again and you kinda lost your prefernce for the Eisbären by then, I`d maybe even recommend going a bit crazy and grabbing a train to Cologne, because the Cologne/Düsseldorf area is definitely the heart of German hockey and that is where you`ll get a real hockey atmosphere. Munich not so much.
