The 3 total Avengers attractions (Spiderman, Multiverse, and Flight Lab) came at the expense of a 3D show (ITTBAB), 3 flat rides, a kid’s train ride, and a playground. Yes the new Multiverse attraction uses additional backstage space, but the fact is the 3 rides came at the expense of 5, not counting the playground as I don’t count Honey I Shrunk the Kids playground as a ride loss in DHS either
The Multiverse attraction using additional space is equivalent to Cosmic Rewind, the Encanto ride, and almost certainly the Door Coaster, since even if it needs to replace Muppets, the ride will almost certainly require a massive show building that uses up backstage space
So no, DL is not doing more on expanding the park than WDW. People are ignoring what it has needed to replace, and ignoring the IP re-skin horror show they’ve created in DCA where the park has barely to do with California anymore. I’m waiting for them to announce it being renamed to Adventure World
