i read the first few pages but my eyes started crossing--if i have a family of 4 and two of us want a Genie+ ressie for a rollercoaster and two of us want a genie+ ressie for another tamer attraction, is that something that we can do at once or do we have to prioritize one over the other? I know i am able to select who is a part of which reservation but if my avatar and my daughters is booked for a return attraction, can i immediately book a selection for my husband and my son?
