My family had jumped in line at around 8pm on an 8:30pm park closing time and the wait was posted at 50 mins, although I think it was less than that for us. By the time we got to the front, we saw that they were organizing people depending on how many people were in your party, so for us, a party of 3 since my sister opted out of it, were directed to the right and was met with a much shorter line than if we had an even number. We probably missed at least 20 minutes of waiting that way. We were on like the 2nd train then. I'm not sure if they do that all of the time, though, since that was the only time we rode it.
