I do agree that it's hard to quantify AP cash spending, but I think it's far less about those items like food and merch as it is tix/lodging as this is the bulk of what disney is tracking when they say that APs don't butter their bread. It's the guests that come in and buy a week's worth of tix for a family of 4. That's their money making machine. They're less likely to stay off property, dine off property and if they're a one and done, they'll go ham on merch. I know that Disney misses the mark on a lot of things, making money and tracking how they can increase revenue, is something they're good at. They're revenues are far greater for the out of town family than the locals who don't stay on property and don't buy tickets. I see very few people use cash in the parks and I would suspect with how prevalent mobile dining is, Disney has more cashless spenders today than ever.
