Sorry I've not gotten a "trip report" done... it's amazing how fast life intrudes once you're back in the real word, but with lots of people leaving, did want to get one suggestion in that we found this last trip.
If you are looking for a good spot to watch Epcot's Illuminations, try over next to the bathrooms at the Odyssey "restaurant" (which is only used for special functions and things now, I think). Kind of on the walkway from Mexico to Test Track.
Anyway, we wound up over there one night with a gentleman who struck up a conversation with it. He was encyclopedic on his knowledge of the parks (would fit right in here) and vouched for our decision. Stand on the walkway across from the bathrooms, 4-6 feet from the "corner". If you aren't in the right place, as soon as it starts you'll see and can scoot over.
It wasn't crowded and you can see well, even the "globe". We staked out a piece of planter to sit on before hand, I went over and picked up quick service from the Mexican area (whatever that new eatery is called there), and "borrowed" the tray to take back over. We ate, watched the fireworks, then I took the tray back.
After that, it's an easy shot out of the park if you're ready to leave.
