hi, we received 3 FP each for attending a DVC presentation. They are loaded onto my magic bands. What is the procedure for actually using them? Do I have to reserve a FP window or can I walk up to an attraction whenever I'm ready and immediately get FP access? Also all of the passes are loaded to my band. Do I scan for each member of my party? What if my party is separated? (Teens off doing their thing and adults doing ours. Will they have access to them?).
