This is a stretch by all means, but I always saw Avengers Campus as harking back to some of the most renowned college campuses in California (Stanford, USC).Mermaids - ocean. Cars - Route 66.
And monsters are still in Hollywood. For now.
It’s like Iger announced “I demand we shoehorn this IP we just bought into the parks somehow”. This is like opening Avland without FOP. But with more restaurants. In the Magic Kingdom.
At least Paris still has an E for it.
Though I know that's just me doing WDI's work for them.
