From Broadway World:
Disney Theatrical Productions today announced that it is extending its Kids Go Free! ticket offer until 11:59 PM on Tuesday, December 23, 2008. The offer, which has generated over $2 million in ticket sales, gives buyers one free ticket for kids under 18 with each ticket purchased to all performances of The Lion King, The Little Mermaid and Mary Poppins between January 6, 2009 and March 13, 2009. Disney has added additional seats to match buyer demand for the performances available under the offer.
All in all a pretty good deal if you can make it to New York City this winter. Visit www.DisneyOnBroadway.com/KidsGoFree for tickets and more information.
