I don't think an attraction of this type (and I.P) are a great combination for a park aiming towards a family demographic in general haha. Infected at Knott's Scary Farm was absolutely horrendous last year on opening weekend. They seemed to work out a decent time-return system by the end of the season though. I just wish this attraction had something more to it to allow for repeat visits.
Infected was only horrendous for two reasons.
1) They critically underestimated how long it would take, therefore cascading the return times into a mess as the night proceeded.
2) The distribution system heavily favored those who knew how it worked and where to go right at rope drop. If you wanted a chance to enjoy it and you didn't get a ticket right at distribution time, you were screwed.
The system was vastly improved this year, making a longer experience, more streamlined, and fixed a lot of the "gun has extra buttons. Oops it's now broken" situations. During the day time it had a very small impact on Camp Snoopy, by design. Given how their park app now shows wait times and has a lot more digital enhancements like e-Tickets, I think they'd have a perfect opportunity to make it an online check-in.
But going back to that at USH, as Jon said, it'd be too slow considering how they just need things to eat up crowds while people are on Potter. I loved Biohazard The Real 2 in Japan, especially compared to Infected, but it was more of a special treat than something feasible. You could easily rework it to handle larger crowds, but you need a larger space to do it, and USH is bursting at the seams already. At best, they could (and this won't happen) convert it into a special hunting event DURING HHN. Design a walk-through that's both passive AND active. That would at least give it a purpose during HHN when otherwise it would be skippable. (As opposed to pumping in wub-wub music)
