There were a lot of times when we would go all the way to EPCOT Center only to find that the park was crowded. Finding a big enough gap was hard and some nights it didn't happen at all. We'd stand in the Horizons load area for hours waiting for a chance. This video is a great example of a short gap. Not much time to document things. Things get much better on our second attempt coming up next.
