I am assuming these will be the exact same kiosks that have appeared at many rides through the Legacy Cedar Fair parks in the last couple of years.
I am surprised that the permits listed it as Flash Pass kiosks, as it was previously announced that the Flash Pass was being retired to be replaced with Fast Lane. For some reason, this announcement was scrubbed from the Six Flags website, and they are listing Fast Lane for sale with Flash Pass listed as on sale soon. This is going to get messy if they attempt to run multiple skip the line programs at once. I personally miss the simple days of one line per ride.
