Numerous cost overruns and construction delays led to the filing of a lawsuit in 2005 by officials of the Kimmel Center against Viñoly. The lawsuit was settled for an undisclosed sum in 2006. A distinctive vaulted glass ceiling encloses the entire structure providing a large common lobby for all the facilities. The Center is a popular attraction, keeping its doors open to the public seven days a week. It hosts thousands of visitors annually and offers free tours of the facility regularly. The Kimmel Center offers a variety of other programs besides concerts, specifically in the field of education. The Kimmel Center is home to its own Youth Jazz Orchestra called The Kimmel Center Youth Jazz Ensemble (KCYJE). This Ensemble includes many youth jazz musicians in the Philadelphia/New Jersey Area. The Ensemble is recognized as a youth version of the Lincoln Center Jazz Orchestra. Additionally, The Kimmel Center holds a Teen Summer Arts Camp annually where it offers ten-day programs in chamber music, choral/vocal music, and jazz.
