The small box on the right-hand side of the screen that contains a Participant's information should include the name of guests and whether their guests have checked in or not. There are many situations where a Participant will check-in and they want to know if there Guests have checked in. The same goes for Spouses. Spouses should also be able to be check-in together. They are plenty of situations where spouses come in together and looking them up separately really holds up the line.
