At first I expected to see hippos with Santa hats and elephants with wreaths around their trunks, but the overlay is much more subtle than that. It seems that the queue area, which has been filled with holiday trees, stockings, lights, and even letters to Santa, got the brunt of the new theming. The actual ride experience relies mostly on special holiday-themed jokes from the Skipper, while the ride itself has minimal changes to the scenes.
But why just read about my take on it? If you won't be visiting the Magic Kingdom or Disneyland anytime soon, then check out this video from Attractions Magazine.
The Jingle Cruise is now open at the Magic Kingdom and opens November 12th at Disneyland.
