Honestly surprised that this has never been implemented given all the other customer-service focused improvements in a post-Kinzel era. When Fast Lane was implemented, it was very clearly a quick way to make profit. The overhead was low (wristbands) and the revenue had to be off the charts, but then the park continued to vastly "oversell."
You'd see rides like Flight of Fear with a regular, slow-moving line and a slightly less long, but still slow moving "Fast Lane" line. Given the experience at other parks and the name having the word fast in it, I couldn't believe that they were letting that happen. Hell, even on Firehawk back in the day (RIP), they'd do one station for Fast Lane one for regular guests with both lines being awful. "Fast Lane" was like 45 minutes for that ride. And the park just kept selling passes all day.
The debut of Fast Lane was typical of that immediate post-Kinzel era: profit placed way over guest experience (or, rather, certain park VPs of "Kingzee's Ayyland" trying to make themselves look good). Given the strides CF has made in recent years, I'm surprised to see the "system" still exists and hasn't been upgraded to something more modern/guest friendly/advantageous (with the other benefit being that guests with a virtual queue are out of line spending money). Could even make it app based... but then they'd have to figure out an app.
