We just got back and had never received our DME info before our trip (my experience said to call but it was during all the Irma problems and the wait was more than 6 hours). When we got to DME we had our magic bands on and there was absolutely no problems! When we got to our resort I just double checked with guest services to make sure our return flight was entered in the system and it was. We received our travel papers for the "tragic express" the day before our departure like every time in the past. No worries!
