I am an Annual Passholder and will be coming down to WDW July 12th staying 5 nights with my daughter, her husband and 1 year old granddaughter. I already have my magic band from my AP but my daughter and son-in-law are cast members and don't have magic bands. I can make fast pass+ reservations but they cannot. We will be getting our resort magic bands in about 2 weeks time and can they use those to make FP+ reservations with?
