All Mitch Snider wants for his family is a traditional holiday feast with the relatives. The problem is that he doesn't have any. That is until he gets an invitation in the mail from his long-lost cousin Woodrow. What follows is a full-course meal of nonstop laughs when the neurotic suburbanites clash with the hippy hicks from hell in National Lampoon's most outrageous family misadventure yet.
Unfortunately the movie Holiday Reunion is not yet available on HBO Max.
