Being that I worked there and used to do crowd control around Mexico for it.... I certainly tell you.... stay away from the mexican pavillion! The bridge is not a good spot. Then you have Norway, clear of trees, but the cantina blocks the view a little. If you are going to use the cantina as your spot, make sure you are seated right in the sticking out part of the terrace, so you get a better view of all WSC. The french Island (on the bridge) is also not good.... the big globe is too far and almost all the times I saw it from there, the smoke was very thick on that side and really disgusting. Same thing, but without the smoke, when I saw it from the Rose & Crown Pub in UK. I also watched it from upstairs the pagoda in Japan, but again, there are things on your way, same as if you watch it from the American Adventure, you can only see one side... From The Italy isola, I´m not sure... maybe the America Gardens Theater blocks the view a little?
If you only have one night to watch it, do not risk it, try to get to the World Showcase Plaza (the area in the middle of the "Tower" shops, right across from American Adventure. It´s a little steep, like a little ramp, people sit, and you are right in front of the globe and fountains, you can even feel the heat of the barge!. Then to exit, it is a lot easier, or you can even wait there for the people to clear, and then walk slowly to the exit while listenning to the soothing music of the park.... aaawwww memories! :animwink:
