If the weather permits, there's a beautiful, big old swimming pool (unheated I'm afraid) north of Kaiserslautern, it's called Waschmühle and a cabbie will take you there for not much more than 5 Euro, perfect for relaxing pre-and post game days and, due to German tradition and hospitality, beer and fried sausages are sold at reasonable prices.
