Group appointments can best be distinguished from individual appointments. With individual appointments, your customers book a service. This means that only one person can book an appointment per time unit. In group appointments, several people can attend an appointment at the same time. Group appointments are suitable, for example, for courses, events, further education, training and much more. 

You can find your group appointments in the navigation under "Appointments"-> "Events".
