Wow... noone picked MINE!!!
ILLUMINATIONS!!!
I get a spot (won't tell where) REALLY EARLY... like an hour and a half early if necessary. I stake my claim. I sit there, eating a snack or meal on the concrete, then when it starts... thats
MY time!!! No one bothers me during illuminations, and everyone in the family knows it. (unless the wife wants to give me a kiss on the cheek... thats always OK!) Its the single favorite reason we do WDW. I have seen it probably 50 times, and it gets better every single time.
I'm not sure really why, but I just LOVE the entire thing from the blowing out of the torches, to the explosive white finale. I've often said that the whole cost of the trip is worth it for JUST illuminations.
I'm not as impressed with Wishes or Fantasmic; only Illuminations; it just seems magical.
But let me explain something else... (not as "pixiedustish") We reserve a seat EARLY. Once it starts, thats my time, and I don't like people trying to push their kids in front of me. They should have been there earlier. I was waiting there patiently while they were riding those last few rides with little or no wait, so now they need to stay where they are and leave me alone. Don't get me wrong, I often let a kid or two I don't know up against the rail with us without being asked, out of friendliness, just don't expect it.
We try to take as little room as possible, but if we were there an hour early don't expect us to squeeze up like sardines for people who waited till the last second. We don't "hog the rail", but if we waited there an hour early, its rude for anyone to think their children should be allowed to just jump in front of us at the last second.
That being said, we also love meeting new people at the rail (also waiting early for illuminations) and just talking. Some of our best memories are with complete strangers chatting against the rails on the concrete.
AFTER ILLUMINATIONS: but BEFORE leaving... is "romantic time". No, not that...

Just simple romance. We find a seat overlooking the lagoon, and since the kids are usually dog tired, they just sit there and rest (they know the drill by now), or they look for bunnies and ducks nearby. My wife and I share a few minutes holding hands staring at the lagoon, enjoying just being with the one person we love the most. Behind us, only a few feet away, masses of tired bodies are fighting for the fastest way through the crowds to the exits. We are miles away in our minds, completely relaxed, tranquil, and silent, and content just being where we are, watching the boats extinguish the last remaining lights in the lagoon. The sounds of the thousands of people fade away completely leaving only the sounds of the waves created by the boats.
Then my second favorite moment at WDW (as a person recently posted) is the walk back to the buses AFTER Illuminations. We always wait till almost everyone is gone, then we stroll leisurely taking in the sights and sounds of Epcot at night. There's an amazing atmosphere there thats completely missed if you "rush out" with the masses of hot, tired sweaty people. You miss all the beautiful lights and the beautiful music if your in that huge slow-moving hoarde of cattle moooving to the front of the park!

You miss all the colored fiber optic lights dancing in the concrete, all the spinning things, the neon lights, the fiber optics, the wind rustling in the flags overhead, and the smell in the air that I just can't pinpoint.
Its just breathtaking.
If any of this sounds familiar, it may be because I actually won a whole lot of goodies (lanyards, etc) from an essay I wrote once on the ambiance of Epcot at closing. It was from a popular Disney website many of you know all about.
