Ok, here's a reprint of a post I made in another thread: sorry for the length
My exprience with the Disney Magical Express is that they should remove the word "Express" for the time being. In brief, the experience wasn't very positive. If you want more, read on.
I dont think they have their act together in planning yet. The time it takes to get between your hotel and the airport is way too long. Arrival took 1 hour 45 min on the bus alone from the time I sat down in my seat on the bus at the airport until I was getting off of it at Coronado Springs. The return trip took 1 hour 15 min, however that isn't including the additional 45 min I had to wait due to buses being severly delayed. A cast member was on the phone at the baggage check area, sounding very frustrated with the DME folks and telling someone that there were several families who were within their flight departure window and needed immediate transport to the airport as the Coronado had not had a Magical Express bus arrive for over an hour, even though they are scheduled every 30 min, so we had missed 2 busses already. Plus, none of us were "scheduled" for a bus as we were told we were supposed to be. The sheet of paper I received the night before I departed, and also a Magical Express person on the phone told me to allow at least 3 hours prior to my flight and "choose a time I'm comfortable with" to be at my bus stop, and be there at least 15 min before that bus arrives. The buses have a scheduled time for each resort that you are provided for that day. Since guests aren't being scheduled for a bus return, the potential for overcrowding exists. This happened at the Boardwalk - with too many guests attempting to get on the same Magical Express bus. A fight nearly broke out between a few people who had been waiting for 2 hours for the ME bus, as it too had not been showing up as scheduled for that hotel. It got pretty ugly with fathers and mothers yelling at each other as to why their kids should get on first.
I understand there can be issues with any new service, and there will be inevitable kinks to work out, however, this looks like very poor execution of a plan from a central planning office - - not a bad system or plan, just people dropping the ball when it came to actually doing what they were supposed to do. My assumption is that there wasn't proper time allowed for traffic delays or luggage loading delays due to guests slowing up the process, and possibly improper staffing at the bag tag processing office as well as with the number of busses and drivers. Since the bag tag issue hadn't been worked out, guests had to bring their own luggage to the busses (both arrival and departure) which lengthened the time.
The problems ran from the still delayed luggage tags (I never got mine), to non-scheduling of return trips, to no one actually having answers to questions that even frustrated hotel cast members couldn't seem to get, to lengthy delays of busses arriving at their scheduled times, to bus drivers who clearly weren't fully trained and ours barely spoke English well, to substantially lengthy trip times from the airport to your resort, to too many stops at hotels instead of the planned "only 3 or 4 resorts per bus" (we had 5 resort stops), and also, from what I hear, there were serious luggage delays in many instances for the folks who actually didn't have to haul their own bags. Magical Express folks lost my info concering my return flight and it had to be provided to them again - TWICE - during my 5 day visit.
It is a "free" service - though of course it's being included in your package in some way, so for that, I guess we shouldn't be complaining. I know they will work this out and it will be a great system eventually, but it was a very rough start and it was painfully obvious that many people involved in Magical Express weren't prepared to start it at this time, even with the past experience with the cruise line process and the many week trial run that had been going on. However, all of these issues weren't isolated, they seemed the norm, not the exception, and it did create a negative situation that disrupts your otherwise pleasant vacaction.
