I don't get it. You have issue with a business for attracting particular customers? Do you go to MK, which is just as crowded, but have no issue with those customers because they are primarily vacationers? Isn't crowded crowded? Or it's the demographic of the crowd that is the "huge problem"?
So let's say they get rid of the SoCal AP's and the CA resident payment plan - cut out what is estimated to be a healthy majority of passholders (albeit Disney does not release figures.) But anway, let's cut these things off and wean out hundreds of thousands of customers. Then what? I'm wondering where the customers come from.
The US population is 319 mil, only 74 mil in the Western US. Of those 74 mil, over half are in CA (39 mil.) But we just priced out a huge portion of them. So where ya gonna get your customers? There's relatively no people in the West outside of CA. And many of them are already your customers. You already have a park on the East Coast. People in the middle can flip a coin. You don't have any nearby continents to draw from. Ya got zip frankly. And in that scenario, there is indeed a huge problem.
