Disney has always had a night time show and celebration at Magic Kingdom (Electrical Parade & Wishes), Epcot (Illuminations), and Hollywood Studios (Fantasmic); but we have never seen anything at Animal Kingdom. As a matter of fact, Animal Kingdom rarely stays open past 6 or 7 PM. This is all about to change. Beginning in the Spring of 2016, Animal Kingdom will begin offering night time activities. Two of the biggest offerings will be a nighttime safari ride, and the Rivers of Light. Disney has put out a great video on youtube, that is narrated by a Disney Imagineer. Clight here, Rivers of Light, to see more.
