I am planning my first trip since the FP+ rollout, and it will be the first time that my 7-year-old won't be riding around in a stroller. My husband is concerned about him getting lost. Are our cell phone numbers stored on the Magic Bands so that they can be scanned by cast members in the case of a "lost parent" situation?

I'm sorry if this is a strange question or if it has been answered a lot already.
