Each portrait session should take about fifteen to twenty minutes to shoot. By scheduling your guests at half-hour intervals there should be plenty of time to get through each session.
When you schedule a date you will be sent sheets that you can use to pencil in the names of your guests at the appropriate times. This should make things easier for you.
It is also recommended that you not have your guests arrive too early. You want them to look fresh for the portraits. Also, if they have children you don't want the children playing and getting wound up and their clothes wrinkled.
