This is the first time our family will travel to WDW with the new DAS system. With the old GAC we were able to use it so my son could ride with whoever he wanted regardless if they were attached to our reservation. One of our daughter's will not be staying with us in our room as she is traveling with her school's dance team and at another Disney resort. Will she have to be present when we receive a return time with the DAS or can we somehow attach her ourselves with just her name or ticket number? We have family that live in the area that come to meet us at the park as well. How do we get the cousins to be able to ride with him since they also aren't attached to our reservation? Do we have to have everyone at Guest relations when we get the DAS initially? Thx
