The festivities conclude in the final episode of the season, with the Tristan family and their winter wonderland full of nostalgic and whimsical characters for kids of all ages in Waco, Texas; the Cheslin-Laneaux family and their display inspired by The Osborne Family Spectacle of Dancing Lights at Walt Disney World, complete with their own dancing light show in Longwood, Florida; the Smaragdis family and their house covered in over 200,000 lights and 13 large dollhouse-style buildings in Indian Trail, North Carolina; and the Athens family with their Christmas display including a mistletoe arbor, Santa's cottage and old-fashioned cutouts in Mt. Shasta, California. Judge Taniya Nayak decides who will walk away with $50,000 and the coveted Christmas Light trophy.
