Let's not kid ourselves though, Disney had the cost of ME baked in to the cash rooms from day 1. ME was also likely baked in to the transportation line items at each
DVC resort. I know I was never foolish enough to assume I wasn't paying for it somehow, somewhere (room rate, resort fee, etc). A one-way trip, assuming full busses, probably cost Disney $5 to $7 per guest, each way including the additional fees paid to BAGS. Charter bus rentals run about $2,000 per day, including a driver. That's the cost to you and me, renting one bus. If Disney is chartering 100 busses per day from Mears, you can be sure there is some serious economy of scale going on there.
I just don't see the benefit of eliminating a service that guests PERCEIVE as free, in lieu of assuming that those guests will be equally fine paying $40-$50 each way for an Uber, especially familes with kids and luggage that aren't going to fit in the cheapest Prius Uber/Lyft. It would be much easier (and look much better) if hotel rack rates were bumped up say $10 per night (discretely and incrementally) and the service (ME) continued.
I get that the original premise was likely to keep guests "in the bubble", but it grew into something that benefitted the guest more than Disney, and in sunsetting the service, it's the guest that feels like someting was taken away.
