I see your points, but I will respectfully disagree that Disney doesn't feel magical. It feels like you are in another world when you are in the bubble. I said in another comment that there are all sorts of "types" of vacations: WDW, cruises, beach vacations, camping, international, etc. None of these can replicate the feelings and vibe of the other ones. They all have their own uniqueness. Me and my family also take other vacations beyond WDW (cruises, beach house rentals, Europe), but none of those vacations feel like WDW. I am certainly not going boycott WDW because they eliminated a shuttle from the airport to the resort, especially when I am sure there are business reasons why (covid, Mears, etc). I also try to be patient when decisions like this are announced, as later announcements usually follow that help soften the blow. For instance, what if Disney offered a baggage service? The train/bus combo would be a MUCH faster option than the DME, so if they offered a baggage service to/from the airport I think that would be an improvement over DME. I remember when the parks closed last year due to covid and all the comments on here were how Disney/DVC was evil and that all our points were going to expire. There was a lot of freaking out going on. I cautioned that everyone should take a breath and give DVC time to sort things out...they aren't out to sc*ew everyone. What happened? DVC announced policies to help everyone keep their points.
I, personally, think Disney is a smart company. I think they are smart enough to know that unhappy customers will take business elsewhere. They also know that keeping everyone in the "bubble" equates to more $$ being spent in the bubble. They have hard data to back that up. I will give them time to figure out alternatives to DME. But that's just me.
