so I'm working on a project right now that involves multi-user persona, meaning that our personas are actually families (more than one person). This is the first time that I've met this kind of user, I tried searching online to find dynamics of creating such persona but couldn't find anything. So I'm wondering if anyone has experience with creating a persona that describes multiple people like families.
 the project I'm working on right now is a home design application, it helps people visualize their ideas and share it with others. As you know, home design usually takes place in homes of couples, mostly families having children. Our approach is that we want users to share their ideas with each other and with an outside community. So what I meant by multi-user persona is people who will be using our product are actually families as a whole, not each person on his/her own. So when developing a persona, I think it's not the right move to consider that eventually each one will be using the application on his own. There are some dynamics between family members involved in home design decisions.
So my question again: how do I develop such a persona that includes more than one user? (Think of Disneyland, most of the users visiting it are families and couples, so trying to think of each user on his own would not be considerate enough) I hope this clears up the confusion.
