Freiden8,
The regulars on here are not being attacking. There have been many posts from people about luggage lost by the airlines and major disasters because medicine or all the diapers, etc. were in those bags.
While Continental may have wonderful luggage service, things happen. We were on a small puddle jumper plane on a flight home. Because of the weight, they had to leave some people's bags behind, to be brought in on a larger plane the next day. This was not a case of "lost" luggage or incompetence on the part of the airline, it was something that was unavoidable and necessary. My mother waited almost 24 hours for her bags because she was unlucky enough to be one of the ones picked. Fortunately, it was the way home, and she had her meds in her carry-on, so it was not a huge problem for us.
On here, posters try to advise you as best they can. As someone with 4 kids, I would also tell you to make sure you had relatively well stocked carryons, because things happen. I worry more about the airlines losing my luggage than waiting for DME to get it to my room.
Since you have small kids, Lewisc and the others just wanted to make sure you packed carryons just in case, so if the airline screwed up or your luggage flew the coop, you would be prepared and not have a disaster trip on your hands. From reading posts on here, I personally trust Disney's luggage system far more than the airlines, and we fly nonstop flights with SW, who generally do pretty well with luggage from what I can tell.
Also, the question was "has DME improved?" as if the 3 hours was because of something they were doing wrong. That is how I perceived it, at least. I think the posters who explained DME is not for everyone and that the 3 hours is not really that much when you consider the process were not attacking you, they just want to make sure that someone who may want to use ME realizes it can be a great thing for some families. We love it because in October, when we get off that plane, I can move myself, DH, 4 kids, my mother, my sister, and my best friend from MCO to BWV without lugging the mountain of luggage I know we will have.
DME can be a great service. Yes, you have to wait for your bags. If that is not acceptable, dont use it or dont tag them, because you will not be happy with it.
