I really, don't understand, "the elitist", "entitled" or PC arguments. Disney isn't "one size fits all". It's why, they offer a variety of services, etc. Why should, some pay for services, they don't need or want? Why should some pay for a service, that everyone uses?
Disney transportation is only partially paid by resort, it's also paid by the park tickets, dining, merchandising, and parking fees. (As well as numerous other departments). All forms of transportation are currently available to all Disney World guests, on-site or off-site (even the resort launches, yes, though during busy times they can restrict to on-site only). This is how it is currently. (I'm just setting a baseline here

).
So, right now, since everyone DOES pay for all the transportation options.
With that said, the elitist comments come out about restricting a preferred method of transportation, that everyone pays for, to one group of select people simply because they paid more for their resort. Now, not everyone considering this option is the elitist either, however, some of the comments have been along the lines of "why should I have to take a bus? I paid more than you did to stay here". Those are the types of comments that bring out the elitist (and similar) remarks.
Can we resurrect our discussion about bringing back E-Nights?
Only if we restrict it based around some arbitrary choice, say, only people staying at resorts that begin with the letters "A, B, and C". (And hey, that covers all ranges of resorts, so no "elitism" there!)
DME...is paid for by all guests..but not all use it. The MK resort monorail is the exact opposite. A few pay, but all should have access?
They aren't taking away, the monorail...only restricting it, during certain times. Big difference...
Everyone pays for the resort monorail, just like everyone pays for the ferry, just like everyone pays for the bus system, just like everyone pays for the express and Epcot rails. They aren't on some special unique account, they're all part of the transportation budget which gets it's money from the other various departments. (While I'm sure some internal accounting does occur, the money from the MK resorts is not likely specifically earmarked for the resort monorail.)
Now, for the span of the hour where both are operating after closing, I would agree, so long as considerations were made for those who have some sort of reason to go to the resorts. This includes ADRs, but also shopping, just wanting to hang around, etc. Though skipping the stop at TTC would help reinforce this from MK, it'd make it difficult for those coming from any of the resorts to get to their cars or going to Epcot* (unless transferring at MK, which would be quite a hassle).
However, I simply don't see outright restricting the resort rail to MK resort guests only during this time as feasible or having a good outcome.
*(Note: this is only taking the 1-hr restriction into account, if MK closed at 8pm and Epcot at 9pm with PM EMH, guests from MK resorts would likely take the monorail to Epcot EMH during this time, hence the increased difficulty on those very same MK resort guests for whom this suggestion is attempting to empower).
