Sadly, I think you're right.. This isn't a "Swarm Backwards" gimmick that we can put down in a few years time.. This is hear to stay. It also must be cheaper in the long run to just create a video synchronised with a ride that can be changed to update it, rather than spending the money on physical props around the ride.. I mean, after-all, the ride could just be in an empty building and you'd be none the wiser.
As for employing more staff, I'm not sure that would help throughput.. It seems from the reviews that the headsets are not replaced to be cleaned, but cleaned in situ; then have to be calibrated etc. I guess it will speed up as staff get used to it and all, but this is still going to be awful.
I'm totally not sold on the idea.. I was 50 / 50 on it to start with, but now.. I'm more "nope". I wouldn't want to wait 3 hours for this experience in the same way I wouldn't wait long for Swarm Backwards either; but then I guess I might be a traditionalist in his mid-30's experiencing life leaving him behind for the first time. It's a slippery slope from here.
