HGTV celebrates the holidays with "Santa HQ," an immersive experience that transforms the traditional visit with Santa Claus into a jingle-filled, interactive journey for all ages at 10 Macerich malls across the country. For more than six weeks, from Tuesday, Nov. 4, through Christmas Eve, Dec. 24, HGTV and Macerich will present a completely reimagined visit with Santa for the 21st century by pairing cutting-edge technology with an authentic holiday experience.
