All this comes back to Michael Eisner making random hotels in random spots of the property. Why carve out an insanely huge piece of land if you're going to segregate everything?
People are complaining about the Imagineers of today building random towers that pollute the delicately crafted skyline and sightlines, but the Imagineers of yesterday decided they needed a fourth park, two water parks, and several resort complexes that are completely separate as if they were social distancing.
Expensive and intrusive additions such as the Skyliner wouldn't be necessary if an elementary level of thought was put into the property decades ago.
Epic Universe will be a mile and a half closer to the other Universal parks than Magic Kingdom is to Animal Kingdom. We can sit here and endlessly discuss the flawed nature of current Imagineers, or realize they may not be as bad as we think when we take off the nostalgia glasses. They're obviously not perfect, but the atmosphere on this forum would lead you to believe that every recent project is done with the standards and scope of Dino Land U.S.A.
