During Presidents Day weekend, with wait times up to the 120's the line spilled right into the center of Tomorrowland. It was pretty crazy.
During the week before, however, the standby line rarely extended past the games. I wanted to try them but I wasn't going to stand around with no line in front of me just to play them.
Also - the corridor in the back of the standby queue is not as bad as people say it is. Yes it isn't themed, however I saw no signs of chipped paint, (maybe one or two spots, tops). I don't like the idea of it being used but I expected it to be in a horrible state and it was not.
