The “emptiness” extends to all the Central Florida theme parks, not just Disney. That seems to indicate it’s not really a Disney only thing. Most likely a combination of factors, but one obvious one is that most people dont’ go to Disney **every** year, they go every other year, or every third year, or something like that, and because of Covid they all revenge travelled all at once, driving record numbers, and now people who did their “theme park trip” in 2022 are doing other things. This is just a reversion to the mean. Disney World hasn’t felt this uncrowded in years, yes, but it’s probably not that much emptier than Disney World was circa 2017ish.
