My dad has an MDE account for him and my mum. My sister has an MDE account for her, BIL and kids. Both have tickets linked and have started making FPs for their upcoming offsite trip.
They want to link them. My dad tried to do this by just adding them by name/age to his. But when he tries to make FP for all of them, it tells him that my sister's family have tickets linked to another account, which they do.
I've never needed to link accounts, so I'm clueless!!!
Thank you in advance for any advice - the simpler the better!
