Hi Darlene!
Your exciting trip to Walt Disney World is just around the corner. I bet your are all so excited. I just love park touring in September, by the way!
Unfortunately, no one knows when the official roll out of the
MagicBand/My Magic+ will occur. My best advice is to keep an eye on the Disney Parks Blog and the Walt Disney World website for an official announcement. At this time, guests are randomly pre-selected by email in order to be participate in the MyMagic+ testing period. Also, there is no particular timeframe in which you might be pre-selected.
Either way, I am certain you will have a fabulous time on your Walt Disney World adventure, Darlene!
Let me know if I can help answer any other questions. Until then, I wish you a truly
magical vacation!
