Probably has been asked one hundred times before but I can"t locate it. We had magic bands on our Oct 2013 trip. Went online to check and it is asking us to customize new magic bands. Our old ones still show active. Do we use the old ones or are we supposed to get new ones for each future trip? Going in March so we have a little time left to customize. BTW I really liked the magic bands on our last trip----7 people for a week with really no issues. When they didn't work at the FP+ they just let us on the rides. That was our only issue.
