When an entire continent is shut down from most forms public entertainment, it's logical that a worldwide entertainment company will cut costs as best it can to reduce losses.
Not really that logical. There is ALWAYS an incentive to cut costs --- to reduce losses and/or increase profits.
A shut down in one unit of the business does not change the incentives as to the other business units.
In fact, must of the cost cutting is built into the shut down --- A shut down park might not generate profit, but it also generates far fewer costs.
Why did Disney World "invest" money into Villains Night, offering extra entertainment over Disney After Hours? Because they know the small additional investment allows them to charge higher prices... and it thereby pays for itself and increases profit.
Reductions in hours can save some labor costs. But also decreases revenue -- less time of people eating in the park, buying in-park extras. Fewer purchases of park hopper add-on, if hours are too short to warrant hopping. Even fewer 1-day ticket sales .... (park closes at 11pm, someone may actually buy a ticket just to enter at 7pm and spend 4 solid hours. But if the park is closing at 8pm, nobody will plan on buying a ticket for a 7pm entry).
It would be equally logical to increase investment in the unaffected parks -- knowing that potential customers are cancelling trips to China, and therefore inviting those guests to spend their tourism dollars in the unaffected parks.
But there is always an incentive to cut the costs that can be cut, without reducing profit. If they can save money by reducing hours, and it doesn't keep away the guests... they will do it. If they can get by with fewer parades and shows...
The push back comes from customer experience and guest satisfaction. Whether Disney World has a parade or not is never a make or break decision about whether someone books the trip. But the more you cut, the less guests enjoy the trip. The less they enjoy the trip, the less likely they are to book return trips... More likely negative word of mouth is generated.
Disney wants the reputation of delivering "magical vacations." If that reputation gets replaced with, "it's like a trip to the DMV"... then in the long term, they will lose money.
It's true that some companies will resort to cost cutting to prop up short term profits, usually to make stockholders happy. But smarter companies simply plan for the long term. As long as they have enough operating cash (or borrowing capability), there is no reason to cut costs just because certain business units are in trouble.
