I recently did an online check-in at Old Key West Resort and the online system would not allow me to complete the check in process unless I assigned Pin numbers to Magic Bands for absolutely everyone on my reservation - including my 8 year old grand daughter, 5 year old grandson and 2 year old grandson. Obviously none of these children will have charging privileges. I called Disney reservations & tech support again and got no sensible answer why minor children with no charging privileges would need a PIN number.
