A mistake is looking at both Wishes and Illuminations as "just fireworks."
They are perfectly timed, layered, firework shows. For instance, they know exactly how long it takes each shell to go up and explode right in time with the music or narration. If a piece requires 2.8 seconds to go up and explode, it is fired 2.8 seconds ahead of that music cue. That's precision. Plus there will be layers of high altitude pieces with low altitude exploding at the same time to produce a certain look. Illuminations can be viewed from all around the lagoon, but best viewed directly across from the American Pavillion. Wishes is best viewed from Main Street directly in front of the Cinderella Castle because the Castle is part of the overall picture. I like to be in the area of Casey's Corner. Worst place on Main Street is down by the Train Station. Yes, you get out of the park quicker but you miss the real beauty of the fireworks show. And that's a big part of why I am there. Enjoy the fireworks, it is not just people lighting some stuff. It is Imagineers that have designed a rehearsed a show for you.
