I didn't say WDW's bottom line, I said the "unit"... meaning the local foodcourt's. I have no doubt that each food outlet at WDW is primarily evaluated on the amount of sales volume and earnings generated at that location.
As for the whole economic impact of the shutdown for WDW, it might not be as bad as you think, and might even be near neutral or even positive for Disney. This might be an interesting discussion. Let me preface what I'm about write by stating that this assumes that Disney doesn't automatically give each person with a ticket that was "active" today a free 1-day park hopper that can be used later. On the negative side, Disney lost out on some food and merchandise sales today (particularly from off-site guests), though people "trapped" on-site are still going to largely pay Disney for food, $13 box lunches or not, and unless it's the last day of their trip people will still have the option to by merchandise while at WDW. They also lost some resort room revenue for people that canceled before the storm, through it appears that others took many of those rooms (put perhaps at a discounted rate). Now let's look at the parks. Since non-expiring tickets are a thing of the past and now tickets turn into a pumpkin 14 days after first use, the clock keeps ticking on everyone's partially used ticket even if the park isn't open today. So the closure today doesn't impact Disney's ticket income, except for the people that would have walked up and bought a 1-day ticket today. The biggest expense for almost any company is payroll. Today, the hourly workers at WDW that operate the parks are largely sitting at home and will not be paid for this "day off" since it was due to an "Act of God." Even though there are a lot of CMs working the resorts, and there are small "ride out" crews at the parks, that's still a BIG plus in Disney's financial column. So basically, you have people with tickets that cannot be used today, Disney will still have a lot of food sales, guests will still take home merchandise, their payroll costs will take a BIG dip this week, not operating the parks today will cut their utility costs, and their rooms were at (or almost at) full occupancy. Unless I'm missing something (and I could be), I don't see Disney taking it in the shorts financially over all of this.
