Something new this year at Disneyland (and the Magic Kingdom in Florida): Jingle Cruise, which brings the holidays to Adventureland.
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.
While it doesn't sound like something that would justify the price of admission alone, it's something new that guests might enjoy during the holiday months. Jingle Cruise joins the other holiday attractions Haunted Mansion Holiday and It's a Small World Holiday.
