I am organizing a trip for my family, parents, and sister's family. In the past I have just used my own MDE for my self, hubby, kids, and mom. With my sister and her children joining us, is it best to just link all reservations on my own vs. creating her her own account that I will be the one logging into and arranging? Basically, I'll be doing the fast pass selections, dining, booking rooms etc. etc. so wondering if there would be any reason at all for her to have her own account.
