Tonight, we say happy 25th birthday to Illuminations. This show made its debut over the World Showcase Lagoon on January 30th, 1988. It continues to be one of the most popular nighttime shows in the world. Other than special holiday versions of the show, Illuminations hasn't changed much over the past 25 years. For most guests, it is a "must do" on every Walt Disney World vacation. My favorite time to watch Illuminations is during the Christmas season. There is a very special "tag" after the finale that is simply incredible.
