I've seen a lot of kids come by and Vortex was their first ever "big boy/girl coaster". They liked it so much they got back on. I would say that they got back in line, but there was hardly ever a line
On a side note, the station would more than likely have to be demolished at least 75% if not completely to make room for the floor mechanics. Yeah, there's room for it right now, but once those mechanics are added, it will greatly diminish the queue side where you wait for what row you want. They would either modify the building and make it larger or, if Rob Decker and his team wants, just demolish it completely and build a new station.
