I have been going to Illuminations: Reflections of Earth each year since it started in 1999, and just this year I noticed that the ideal spot for seeing the show is right in front of the entrance to World Showcase. I know that you can see the show from anywhere around the lagoon, but it wasn't till my trip this year that I saw the show from the front, and everything is symetric! From a different point around the lagoon, you see fireworks and fire and stuff, but it doesn't seem to be set up in any certain way. But from the front, it is much different. It is hard to explain if you don't know what I am talking about, but I think it looks much better if you watch it from the front, providing you get a spot early enough! It shouldn't be too hard to get a spot there if you are willing to miss the Tapestry of Dreams parade, because it doesn't come around there, and everyone else will be going further into WS to see it.
