I'm part of a 6 person bachelorette weekend in Disney. We've decided its best to have one person handle fast pass, dining reservations, magical express, ect. and I, being the most knowledgeable, have been elected as "trip mom." Honestly, I'm excited about it cause, well, I'm a member here, lol. the only issues is the girl who originally made the room reservation has already connected it to an MDE account. If she hasn't done anything else can I still attach it to mine and do everything else? I've never had this issue before.
You just can't cancel any resort reservation or ADR that she has made. We do this all the time for my husband and son who have their own MDE accounts.
