Duff Goldman wasn’t shown going on holiday; he was missing from some Season 12 episodes of Holiday Baking Championship because he left early and then was said to be “under the weather,” not away on vacation.

What actually happened

  • In the December 8 Season 12 episode, Duff tasted the bakes but left before the results; host Jesse Palmer joked that Duff had gone to a “Chrismukkah party.”
  • In the following episodes, Duff did not appear at all, and Stephanie Boswell and later Zac Young stepped in as guest judges.
  • On the finale, Palmer told viewers that Duff was “still feeling a little bit under the weather,” which is the only in‑show explanation given.

Was he on holiday somewhere?

  • No official source says Duff was off on a specific holiday trip or at a particular location; the “Chrismukkah party” line appears to have been a light on‑air joke, not a documented destination.
  • Entertainment coverage and fan discussions only confirm that he left mid‑episode and then missed the semifinals and finale, with illness mentioned as the reason, not travel.

What Duff has shared publicly

  • Around the same time, coverage noted that Duff and his wife are expecting their second child and that he recently opened his D’s Del + Market shop, but this still doesn’t tie him to any specific holiday‑trip location during filming.
  • He has posted normal holiday‑season updates on social media, and there has been no official statement tying his absence to a particular vacation spot.

TL;DR: The show only joked about a “Chrismukkah party” and later cited him feeling under the weather; there is no reliable information that he was on holiday anywhere specific during Holiday Baking Championship Season 12.
