National Lampoon’s Christmas Vacation kicks off at 1 PM on Sunday, December 16.

Admission is $5 per person, and the box office will open at noon. Tickets are available only at the box office just before the show.

The comic misadventures of the beleaguered Griswold family continue as America's most dedicated dad is determined to stay at home to create "the most fun-filled old fashioned family Christmas ever" -- but life has a particular way of throwing wet logs on Clark Griswold's fire. Starring Chevy Chase, Beverly D'Angelo, and Johnny Galecki.
