The biggest problem with this new service is not that the details have not been released to cast members, but rather the cast members don't read the information, or don't pay close attention to it. Many cast members (and consequently guests) think that this is just a Mears Shuttle with a Disney painted bus. FAR from it.
With the Mears Shuttle, you have to wait for your bags, and then head to the check in area. With DME, you head straight to the check in area. Check in will take on average 90 seconds, and you'll be directed to the boarding area.
With the Mears Shuttle, people can just walk up to the shuttle and get a walk in reservation. With DME, you MUST have a reservation 10 days out. This way, DME will know approximatly when people will be arriving, and where they are going. With DME, they will know that no more guests for a certain route will be arriving anytime soon, so they can dispatch the bus earlier without waiting for it to fill up.
With the Mears Shuttle, the driver has to load and unload a lot of luggage. With DME, just carry on items & strollers.
With the Mears Shuttle, the bus will make up to 4 stops at the airport. With DME, the bus will only have ONE pickup location at the airport.
With the Mears Shuttle, the bus will stop at a few offsite resorts, and then a few onsite resorts. Who knows where they will go. With DME, there will be 5 routes, 4 with three stops, and 1 with four stops. I don't know the exact routing just yet, but for the most part, the resorts will be lumped together based on proximity. (ie: All three All-Stars on one route, the MK resorts on another route, ETC)
With DME, the resorts will be sent a message letting them know you will be arriving. This way, they can prepare for a shuttle dump, and staff the front desk better. (ie: CMs take thier break before the shuttle arrives)
With DME and selected airlines, you can check your bags and recieve boarding passes right at your resort. DME will pick you up approximatly 2hrs 45 mins prior to your boarding time (give or take). This is no longer than if you were taking any other form of transportation. Orlando International Airport recommends that you arrive to the airport 2hrs prior to flight time. And it could potentially take 45 minutes to get to OIA from a MK resort.
So let's summarize this comparison:
Not waiting for bags saves you time.
Having a reservation, and knowing when best to dispatch the buses saves you time.
Only making one stop at the airport saves you time.
On
average, you will probably only have one other stop before reaching your resort, which saves you time.
Sounds a heck of a lot better than the Mears Shuttle to me
In regards to the bags being delivered, it's the same deal. Disney will know whos bags will be arriving and when, so they will best be able to coordinate how that will run.
