We have a group of 10 (+baby) going down in November. My wife and three kids are managed by me, along with my mother-in-law. My brother-in-law and his family are all managed by him. I know it's recommended that all the adults have their own MDE accounts, but I guess I don't quite understand the difference. If my MIL goes around with BIL's family, will they still be able to make same-day FP+ for her? We're all friended up on MDE. What exactly are the drawbacks of having an adult be "managed", instead of having their own account?
