alliecats, they have changed Illuminations since you saw it... in 1999 they premiered a show called "Illuminations: Reflections of Earth". People seem to be divided over which they prefer... but as I never saw the original version, I have nothing to compare it to. I did see Reflections of Earth last year, and it was stunning and beautiful. We're going to try to see it twice this trip.
Last time we were right along the railing on the north side of World Showcase Lagoon, between Mexico and the bridge to Future World. It was nice, but we're going to try for a spot on the southern end next time so we can see the "globe" better.
