I get the regular theme park and how it can be made profitable with the guidelines, but things like Haunt have tons of extra labor that have to be paid for somehow. Like I said, I think making it part of the normal operating day on a very much scaled down version may be the way they will end up having to go.
I think there is
probably a way they could do it. If I had to guess, it'd look something like:
1. Much lowered capacity - Maybe the biggest issue is just how packed the Haunt is normally, and especially so the closer to Halloween you go (I honestly usually end up going the weekend before out of tradition). Even if capacity numbers are raised by that time, which is no guarantee by any stretch, Knotts can't really afford the negative publicity if they go with their usual "pack it in" strategy. I'd guess they cut the normal capacity in half to stay safe.
2. Price increase - I mean, this was probably going to happen anyway, but with the lowered capacity they can charge a more premium price to try and offset costs.
3. Virtual queues - This may be a bit harder to pull off, if only because my experiences at Knotts have always seemingly included poor cell coverage for some reason, but limiting the amount of people who can physically be in the queues at any one time could go a long way to satisfying the public.
4. Less mazes - Part of the cost cutting, but paring the roster down to a solid 6-7 mazes can cut down on production and labor costs. To that end, they could also limit the areas that will run mazes to only backstage areas if they so choose, and theoretically consider going the Magic Mountain path of having the park just continue operations into the night, but with an extra charge to go through the mazes.
4b. Less focus on scare actors and more on atmosphere/animatronic scares - Doing this as a sub-idea because it would lower labor costs for scare actors by requiring less of them. It's not something I would enjoy, as I'm more a fan of the way Knotts utilizes their scare actors instead of the "boo box" style you find prevalent at Universal, but for a one-year fix, this could help.
5. More ride overlays - This would be a simple workaround to less mazes, which is to add more special ride theming. We already get the Log Ride, and they could bring back a Calico overlay rather easily. The new Bear-y Tales should be open by then, right? They could program a switch (similar to what Disney does with Guardians during this time) for a "spookier" version of the ride. Maybe something for Bigfoot as well?
There's probably some other changes you could make that I'm not thinking of (maybe regarding how food/drink is done or creating premium dining experiences to bring in more money) but as a base, I imagine you'd see something like this.
