Hope you noticed more improvements. Rode it weekly since opening weekend, and there were noticeable improvements to how they operated it. First week was bad, left in the dark on the stairs between pre-show and the train. Then my VR headset positioned itself under the train, I only told staff after the first section as it was interesting seeing how they set up the animation, which is better than most Vive VR content. Completely missed the mid section, then we stopped half way through the final section, making the ending really anticlimactic.
Later weeks we now had staff at the hold between pre-show and the train, who all now make a point about the really good visual effect you're about to see but probably won't notice. There were a few more physical effects in the mid section. On my last run through they had changed how they operated the lights, with a more sudden light to dark which made the initial part of the show work much better.
I even saw it one Sunday with a walk on queue! But sadly I also saw it have to evacuate people out the back a couple of times too.
