The point is, if Disney execs don't want to encourage return guests (which is a major conjecture regarding why they are making so many CUTS in staffing and services at this time,) why would they, at the same time, try to encourage locals to fill up the parks?
Confirmation of said item in your bolded text? I'm not following.
Park revenue is more than ticket sales. It's everything purchased within the park - food, merchandise, rooms, etc. Locals without passes may not consider going because
ticket prices are high (for example - it's a lot to go for just one or two days), but if they reduce admittance costs with special deals but not all the way to passholders, there's an untapped market segment now entering the park and purchasing the food, merchandise, rooms, etc.
There is no confirmation as to whether or not a local or tourist will spend more money. A tourist goes once in a life time (unless they're like us on the DIS), but locals can go multiple times and while they pay less to get in, it's possible over time may spend more in food, merchandise and the like.
I am in Southern California and may be using too much
Disneyland logic on this -- but this is the impression that I've gotten over the years. At Disneyland we have the Southern California Flex ticket promotion going on -- 3 days at a park for $180 - or $60 per day. It's bringing locals who have been priced out of the park, but they're doing FULL DAYS, complete with three meals and some character experiences, plus buying merchandise. It'll be interesting to see how the California Adventure Food and Wine festival will be impacted with attendance - I'm sure the price per visit will increase as that promotion happens during the month of April.
But similar logic should apply to Florida. Previously untapped market segment, sweetening the deal, and the profits are increased. Taking the hit on ticket revenue but gaining food sales and merchandise purchases in the long run is still a profit overall.
