We are headed down in two weeks and I got to wondering about having multiple magicbands active at the same time. I see that my band from our trip in 2015 lists as active and I just received our new ones for this trip. Will both bands be usable at the same time? I would love to have an extra band for access to our room for other members of our family who will be staying at the same resort. The same goes for my sons band from our last trip that holds all of his scavenger hunt levels that he achieved last time.
