I binge-watched 'Good Luck Jessie: NYC' a while back, and from what I recall, there isn't a standalone holiday special. The show had its fair share of festive episodes though, like the Halloween and Christmas ones sprinkled into the regular season. The Christmas episode, especially, had that classic Disney Channel vibe—sibling shenanigans, heartwarming moments, and a dash of NYC winter magic. It wasn't branded as a 'special,' but it definitely delivered holiday cheer.
If you're craving more seasonal content, Disney's other series like 'Jessie' (the predecessor) had fuller holiday arcs. Still, 'Good Luck Jessie: NYC' packed enough festive fun into its episodic format to scratch that itch. I kinda wish they'd done a full-blown special—imagine the Jessie crew ice-skating in Rockefeller Center!
