The Washington National Opera finished its season with a $2 million surplus. But it was a tough season for patrons. The company spent the first half of the season in temporaryt quarters at Constitution Hall While the Opera House at the Kennedy Center was undergoign renovation. “Opera patrons, who paid up to $285 a seat, said parking was murder, the bathrooms were remote, and some sections of the hall were a sweat box. The longer the opera stayed in Constitution Hall, the more operagoers stayed home.”
