You're missing the point. I'm not talking about nostalgia, or the overall park experience, I'm talking about the real-world functionality and technology of the accommodations on property. The functions people expect to be contemporaneous with their current time frame. By 2042, the homes we all will be living in will be far more advanced than anything we have now, and we will expect at least that same level of advancement in our premium resort accommodations.
If you were going to WDW tomorrow, living your everyday life with 2022 technology, would you be happy with a room that has a black and white TV with a rabbit ear antenna, a refrigerator/freezer with ice cube trays, no USB ports, no WiFi (or any internet whatsoever), no email (just send this signed credit card form back to us via USPS), and a bank of rotary dial pay phones in the lobby. No hair dryer, no microwave or coffee maker? At the rate of technological advancement, a 50 year look backwards is likely a 20 year look forwards.
Now, add to that the advancements of building technology specifically (self-dimming windows and sliding glass doors, sound and thermal insulation double what we have today, smart HVAC, lighting, and other building systems) that will surely have made it into residential home construction by that time and will be the expectation not the exception.
Everyone want's to drive Route 66 and stay in an authentic "Route 66 Motel". That is, until they get there and see the reality. For the rest of the trip, they're looking for the nearest Hilton Garden Inn at each stop.
