@CaptinEO is right, it's too much tech and complications for more people than some here (and at Disney) seem to realize.
People don't associate theme parks as places where they need to use a lot of tech to make decisions period, let alone just get into the place.
Adding to this issue, Disney's current apps are anything but intuitive or user friendly.
Disney used to be experts at a frictionless experience; now they're piling friction on like toppings at an ice cream sundae bar. I find the parks less user friendly than they should be, and I go more frequently than many others. So I can't blame infrequent visitors or people who aren't tech savvy for being overwhelmed, especially when it is Disney that is the primary reason these problems exist.
I'm not saying that there shouldn't be ANY tech or app use, but they are creating unnecessary frustrations and friction by essentially forcing people to use tech to do almost anything at the parks.
