I posted a couple of shots of the Fountain of Nations back in December 2012 from our trip last summer. These shots are from New Years Day 2013. These photos were taken at night after I watched the The IllumiNations: Reflections of Earth Fireworks Show. I waited around in the park for a while to let people leave and proceeded out slowly taking photos.
The fountain sits in the open space between Innovations just after you pass Spaceship Earth as you enter the park from the main entrance. The fountain is elevated and water is shot up in the air and timed to music. At night their are lighting effects added. As a result this is a great spot for night time photography.
I was able to obtain the following information from A Glass Slipper Vacation Website: ”Another fascinating fact about the Fountain of Nations is that representatives from 22 different countries poured water from their native lands into the fountain.”
