The vast majority of guests have nothing but good experiences with DME. Do some people have a less than magical experience? Sure. But, people have bad experiences with town car services that others have had good experiences with. There are always going to be people that have a bad time of it.
I'm not sure what the comment about 'it takes beyond midnight' means. Is that when the luggage appeared? If so, nothing unusual about that. If someone lands at 8pm then luggage being delivered at midnight is perfectly with the norm. You may not like it, but it's within the norm.
And the comment that people have been told that luggage delivery time begins as soon as you land? Nope. I quote from my current DME statement..."Luggage delivery may take up to three hours after you arrive at your resort to be delivered to your room.'' It doesn't say anything about resort checkin (as it used to) or if you're already checked in by someone who has been there for two days. I think we pretty much have to go with what the official statement, from Disney and DME, says.
So, in short. No, DME isn't always going to be 'magical'. It can be nightmarish. BUT.....as I said, the majority of the time it works just fine. I'm not sure what anyone thinks can be done to make it more 'magical'. If they start running more frequent buses, so guests don't have to wait more than 5 mins (either in line or on the bus), then the cost is going to have to come from someplace...and that will be room rates. And I doubt anyone wants that to happen.
DME is not for everyone. If you have to be at the resort in a short space of time, or you just don't want to partake of mass transit, then either rent a car, or book a
private car service. But saying the system is broken is not fair. It isn't broken...it just doesn't work for every single guest. And each guest can make a choice as to how to get to and from their resort.
