From Disney Park Blog:
We just got word from our friends in Walt Disney Imagineering that an Adventureland attraction will receive its first-ever holiday makeover this year. Beginning in early November, Jungle Cruise at both Disneyland park and Magic Kingdom Park will temporarily transform into “Jingle Cruise” for the holiday season!
In this new seasonal storyline of the attraction, the Skippers have grown homesick for the holidays, so they’ve added holiday cheer to the Jungle Cruise queue and boathouse with decorations that have been mailed to them from home (plus a few they’ve created themselves). The Skippers have also added a slew of new jokes to their tours that are the perfect way to get guests in the holiday spirit. Additionally, Jungle Cruise boats have been renamed with the holidays in mind, and if guests listen carefully, they may hear a holiday-themed radio broadcast playing in the background.
Jingle Cruise will begin launches in early November at both parks. Be sure to keep your eye on the Disney Parks Blog for more updates!
