I've noticed that lots of people here like to support their opinions with something like, "that's just a fact."
At this point, Disney seems to have acknowledged that they're just going to keep raising prices until crowds thin out.
I would love to see some cost/benefit analysis for Disney between a full park at $200/person vs. half as many guests at $400/person. I would expect a full park of guests to spend more on food/souvenirs, but with thinner crowds, maybe a half-full park could generate more profit? Maybe people would slow down, be in better moods, and spend more per person?
Fewer guests would require less staffing, maybe lower operating costs, allow more/better interaction between CM's and guests, and would probably result in higher customer satisfaction. It'd be interesting to see where the tipping point might be.
