FYI, I am going to WDW in late Sept. I have my info and reservations on the website "My Disney Experience". When I signed in today to look up something, it told me to choose our Fast Pass Pluses for our trip. I was able to choose 3 per day for everyone and could have also chosen to have the magic bands. However, I didn't choose the bands because I'm not sure if the kids would like them. So if you have a trip planned, you might check My Disney Experience and see if you get the offer too.
