Heres how I believe it works, you would each need your own package because while you can share group pictures you couldn't share family photos. For example if you take a big group picture on pirate night you could all purchase as part of a package but if you all take individual family pictures that would only be linked to one room therefore only the person with the package attached to that room could buy that picture. You couldn't buy a picture of the other rooms family because it wouldn't be linked to yours. Hope that helps and maybe someone can clarify further for you!
