You raise a good point....I wasn't thinking it from the angle of resort check in or dining discounts. I was only thinking in terms of park entry.
First thing would be to try and transfer those singles to one person.
There is for sure a work around on this. I've got magic bands linked to three different
MDE accounts and none of them are linked....so on paper I'm three different people with different tickets. I have used multiple bands on the same day. A totally separate MDE account just for that AP might the answer.
ETA...for park entry, as long as no finger scan has been attached to the tickets it does not matter who uses them. Perhaps a phone call to find out the status of the singles....and maybe that person could transfer them all to one person.
