Kicking off this list is the musical boat ride of global peace: It's a Small World. Mainly for its holiday version, which runs from early November through the end of the year. As you travel through the ride, the 300+ animatronic children representing countries from around the world sing "Jingle Bells" and "Deck the Halls" instead of the standard "It's a Small World." The beautiful lights also add to the experience. See this if you can, even if it's not during the holidays. It's one of the rides you need to say you've been on. Opened May 28, 1966 at Disneyland and October 1, 1971 at Disney World.
