We like to watch Illuminations from either Mexico at the resturant on the water (can't remember the name) or if your in the United Kingdom by the Fish and Chips place, there is a path that goes down to the water, great place to watch and not alot of people there, but as suggestion in a previous post, pay attentiong to the direction of the wind.
Fireworks at MK, we like to sit at the Plaza Pavilion, on the lower level right by the wall, you need to get there early though, these seat go fast but it is a great view and Tink flys right over your head.
The Jammin Jungle parade at AK, we like to sit right by entrance to the Island Mercantile store, this way when the parade is over you can either bolt down the road to FOLK or you can cut through the store to the exit and avoid the crowd behind the parade, or sit right at the entrance to the Safari, this is where the parade starts and as soon as it ends, you can jump on the Safari with no wait.
