Right now, when you enable "add guests" in the service calendar, and you test it by adding multiple services for 3 guests. The duration doesn't add up, the calendar thinks you're treating these guests all at the same time so it only selects the duration that is the LONGEST from one of the services. Can there be an option where it does the services one after another? As, for example, there will only be one employee that will be doing services for the group.
