Disney's Animal Kingdom hasn't always been an all day Park, however over the past couple of years nights in this Park have taken on new life. I am a huge fan of Animal Kingdom after the sun goes down. It wouldn't be a Disney Park without offering a fantastic nighttime show, and Animal Kingdom offers Rivers of Light. Rivers of Light is the Animal Kingdom's first-ever nighttime entertainment offering, lasting for 15 minutes and combining storytelling, brilliant visuals, and a grand musical accompaniment.
