Jason Dodge brought this up on his podcast, not sure if he posts here. I'm sure someone like @ParentsOf4 would have the actual homework to back it up.
The argument is hotels and food are not more unreasonable than they have been in the past. They've always been pricey, but largely track with inflation. Some of Disney seeming extra expensive in these regards is trying to normalize pre-inflated prices to where we are now.
On the other hand park ticket prices are the major culprit. They've essentially doubled, even accounting for inflation, in the last 20 years. Even if the ticket increases have been more 'modest' the past few years compared to inflation, Genie+ was just the latest scheme to increase the ticket price march.
I think we've reached the inflection point on ticket prices - which really means the solution isn't to keep increasing prices (they risk pricing people out entirely, if they haven't already). I think the executives are starting to realize this finally. But to increase WDW revenue moving forward, they need to expand the number of guests via attractions and new capacity.
Single-day ticket prices have more than doubled since 2005, 7 day park hoppers are closer to a 200% increase along with APs. The problem now isn't that they are "raising ticket prices", but instead shifting what days gets charged what amount in a pathetic attempt to claim "we aren't raising prices!". It's pretty damn disingenuous to claim that when 5 years ago you had (as an example) 120 days at your lowest price point but today you have 12. And the value for what you are paying for has diminished as well. Bob has been milking nostalgia for over a decade, and milking the **** out of it. Eventually the milk will run out.
