The family favorite “Madeline’s Christmas” and David Sedaris’ comedic gem “The Santaland Diaries” will return to Horizon Theatre this holiday season to entertain young and old alike. While “The Santaland Diaries” turns “ho-ho-ho” into “ha-ha-ha” giving adults-only an antidote to the holiday blues, Madeline’s Christmas is holiday fun for all while 12 girls in two straight lines navigate getting home for the holidays. Jump starting the Christmas season Nov. 21 will be “The Santaland Diaries.”
