You keep suggesting I'm telling Disney to turn away business. No, I'm telling Disney to monetize their admissions vs taking the sweetheart deal up front because the deal breaks down. Stop promising 'all you can eat' and instead monetize actual usage.
When someone can casually come in and just hang out from 5-9pm and then leave... that is WAY more expensive for the park to absorb than a guest that may come from 10am-9pm along with the regular masses. The latter is also more likely to spend in the park, while the former is just gonna do a few highlights and go.
If each admission were actually a cost in some way... people wouldn't treat it like a throwaway and would likely consolidate their visits more. And in doing so, they stay longer, which increases the chance of spending, and go through things like parking more like tourist guests, etc.
All of the above is how 'free on demand' 'all you can eat' admission impacts the park on a weekly basis in a negative way. The whole hordes descending on the park for a high profile date are another beast. But the premise is the same... 'bodies in the gate' are not equal. How they get there, when they get there, how long they stay, and their spending motivations all make a 'body' cost different and represent different revenue opportunities.
Thinking 'Disney should not turn away a guest' is an oversimplified view that doesn't take into account the cost vs revenue opportunity of each guest and optimizing your attendance to be the ones who will actually give you the most money per head.
