It's A Small World is a classic ride that originated at the 1964 New York World's Fair. It was eventually transported over to Disneyland. When Walt Disney World opened with the Magic Kingdom, It's A Small World was one of the original rides. The main difference with the Walt Disney World version and the Disneyland version is in the ride queue. At Walt Disney World, the ride queue is indoors vs. an outdoor queue at Disneyland. I also think that the boats are wider at Walt Disney World than Disneyland. Both versions of the ride are equally enjoyable. I took video of the ride when I went with my family in December 2009. Enjoy the video!
