MK offers "Wishes," the largest fireworks show in Disney. Tinkerbell starts off the night by flying down from a top of Cinderella's castle. Then the fireworks begin and are choreographed with classic Disney favorites. It's a must see!!!
Epcot takes the fireworks one step further adding lasers, fire, and images on a globe above and on the World Showcase Lagoon. The night starts with a guy (don't know who it is) telling a story, all the torches around the lagoon dim and the fireworks and lasers begin. Then, a large globe floats to the center of the lagoon with images from all around the world being displayed - like a large television screen. This is all done to music which makes this a very magical show!
MGM has more of 'show' event at the end of the night - "Fantasmic!" Take many of the elements used in the other Disney shows and add in dancing waters, special effects, and Mickey fighting villians. It is very awesome and yet another must see!
