Before I go and close this thread, since the info is in that stickied thread...thanks to those of you who posted links to it....just let me say one thing.
Can you use DME for luggage only? Yes..it has been proven time and time again that it is not a problem. The issue is that if you, any one of you, were to call Disney right now, and ask them if you can use DME for your luggage while you get yourself there in some other way, Disney will tell you no, you are to ride the bus..that luggage transfer is an additional perk of using this service. That it is,first and foremost, a service to get guests to their WDW owned resorts without having to pay for a shuttle service...the luggage transfer is a perk for using this service. THAT is what Disney will tell you. But, they do something completely different than what they say. They will grab all bags that are tagged with those yellow DME tags,and get them to your resort, even if you have rented a car, or hired a towncar service or decided to ride your yak to your resort!! That's the bottom line. Once again, Disney has put out a ruling but doesn't enforce it. Just like refillable mugs.
And now....it is closed.
