I have no problem with Disney making a profit - without profit, a business ceases to exist. What I do have a problem with is Disney making a profit off the theme parks, to the tune of $5+ billion over the past couple of years, and then paying token attention to them. How much of that profit has been funneled back into the parks, WDW specifically? The Fantasyland expansion was/will ultimately be paid for with the increased ticket prices Disney instituted while it was still being built. At least that can generate some revenue - How much revenue has the much-maligned FP+ generated, compared with how much it ultimately cost?
What ticks me off the most is the mindset TDO and the bean counters have - "It's 4¢, they won't even notice it!". Or... "They're tourists, what do they know?"
