There is something very different from a local haunt that only does a short-run event every 2-3 months (while relying heavily on volunteers), and a 365-day event with four distinctly designed haunts. Unleashed can’t really do seasonal changeovers to the houses. They can’t get “surges” outside of October. It’s not like they can throw a Santa hat on Leatherface.
Unleashed is basically a “locked” experience. Any house change would require its total options to decrease for 4-6 months. It’s a situation where its primary option for improvement will also involve a long-term subtraction. That means its total HAS to be exceedingly high to begin with to survive that period of loss. First impression is that it’s not high enough. That means those subtractions will hurt… bad.
This doesn’t even acknowledge the fact that Vegas, as a vacation destination, is starting to hurt. Tourism and spend is markedly down (and trending to continue down). The fatalism is coming from a legitimate place.
