Actually.. but your own argument, if everyone DID do something about it, the prices would change. The problem is when the bulk of customers just roll over the change is seen as accepted and the process repeats.
You did set the tone that if you aren't OK with the prices, then something is wrong with you. People in this thread even go as far as the cliche 'maybe a disney vacation isn't for you'... which basically says "If you care about value, or your money, a Disney vacation isn't for you".
I'm not an uninformed customer - I've done manufacturing, I've done product development, I've done sales, I've done marketing, I've done pricing. I know the concepts in play. And I also know the consequence of 'captive audience'.
Just because you CAN do something doesn't make it the right thing to do by your customers.
Yes Disney has tons of overhead that is not directly monetized and needs revenue from other activities to fund the beast overall. But your HM analogy falls down when you compare Disney against itself. The HM has been there all along, and the model that supported it is generally the same... yet price escalation in things like food have outpaced the rest of the model and Disney's own fiscal results show higher margins. So it's not 'we gotta pay for this overhead' - its 'what can we charge and keep the chart going the correct direction'
