What I've heard is they need to replace a specific part (projector lens or something like that) and since the original manufacturer is no longer around, they have to find another company to produce a custom replacement part. Also, it's not cheap. Something like around $50,000 and with COVID, it's really factoring in to their budget. I get the feeling that if they can't find that replacement part, the show will not return.
On a side note, Mrs. Knott's fried chicken is being offered as a rotational menu item at Wilderness Broiler for the next two weeks for all dining plans. Is this the first time Mrs. Knott's fried chicken is offered inside the park? Nice knowing my dining plan is eligible for this option. I've always wished their fried chicken was offered on the meal plan. Even if it's only for two weeks, I'll take it. It might be a smart marketing move to get those who've never tried Mrs. Knott's fried chicken to get exposure and open up more sales for Mrs. Knott's fried chicken restaurant or their to-go spot.
