Hello,
I am an Administrative Assistant at a university research center. I moved departments recently to a new job and I'm not used to scheduling at this scale. Before, the largest meetings I scheduled were maybe 8 people, tops.
Our lead wants to have 90-min monthly meetings where ideally the admin on our team (him, co-director, myself, 2-3 other employees), 6 PIs, their various lab members (~13 people), and 2 other people from another key center join. If people can only attend part of the meeting, that is okay.
I can see Google Calendars for our lead/my team, and the 2 from the other center. 3 of the PIs claim they have accurate Google Calendars (don't quite think they do) but the other 3 do not and prefer to be emailed directly to schedule.
I used a whenisgood poll and found a date almost everyone but 3 PIs could make. All their labs are represented regardless.
However, my lead wants an alternative that prioritizes the 6 PIs. The only thing I can think of is to go back to the whenisgood, remove the responses from all less relevant people, list out all the times most PIs said they could make it (because there isn't a single half hour all of them can make) in 90 minute increments and ask if they could make all or part of those times. And hope the answer is favorable.

This is...probably more information that you needed. So I guess I'm asking for tips on how to untangle this specific situation, and what else I could do for future monthly meetings so this doesn't happen again.
