There's no such thing as luggage tags for the return home.
You need luggage tags for the way there, because when your checked, tagged luggage is unloaded from the airplane at MCO, the responsible people know to "pull" each DME-tagged bag and put it into the DME luggage system
On the way home, you do one of two things, check your luggage with Resort Airline Check-In (if you are flying a "participating" airline) or bring it to the bus yourself and get it right back as soon as the bus arrives at MCO. If you're using RAC, the person there tags each bag with the actual official airline/TSA tag, the white tag that has the 3-letter airport code on it. This can only be done at the time you check your luggage, so there would be no benefit to your having any sort of DME tag at that point. If you're taking your luggage to your DME bus, there's no need for DME tags because DME will not be handling and delivering your luggage -- you hand it to the driver, the driver stores it under the bus, when you arrive at MCo the driver unloads the luggage and you take it and bring it to your airline's ticket counter.
