I scheduled large one-day events where attendees were recorded performing voiceover several times during the day. As many as 350 individual recordings throughout the day, each with an acting coach, studio engineer, studio room setup, custom sets of scripts, and a demographically optimized group of attendees that would go through the day together. Because each attendees journey through the day was (somewhat) customizable by them, each new attendee would change the schedule of some other attendees. So we would have to wait until ~80% of the tickets had been purchased to begin scheduling, each new attendee was progressively harder to schedule (making it hard to keep selling tickets), and we had to also be flexible with the support staff, engineers and coaches.
