Interesting. I wonder if there were other people on the ride, like in one of the scenes, when it stopped, and what they did. I am asssuming it stayed stopped.
I know one time when there was a hurricane coming, they evacuated the campers from Fort Wilderness to other hotels (I think they said at the time it was primarily the Contemporary, not sure though).
Hope everyone heeds the watch, and pays attention this time.
As for storminess in general, and hard rains (sans a tornado watch or warning), I always try to bring an umbrella -- as sort of my "insurance" against rain. (You know, if you have it, it won't rain; if you don't, it will!) But no matter what, I consider EPCOT the worst place to be in a powerful rain. There is simply NO way to get out without crossing major lengths with no cover. As those raft rides always say, you WILL get soaked if you try to go anywhere in EPCOT during a rainstorm. LOL. (I just go into one of the films or American Adventure and enjoy the show, or sit down for dinner and wait for it to subside, but sometimes you can't help it and you have to leave -- in which case, you WILL get soaked! Unless you have your umbrella!)
