Out of 12 cruises, I've only been to one FOD meeting. It was on the Golden Princess on the western Caribbean itinerary. About 10 of us showed up plus the cute assistant cruise director. He's the one I had asked the day before if one was scheduled, and he told me that it was already on the schedule.
He bought a round of drinks for everyone. We basically chatted with everyone for about 45 minutes. We had to leave the room because a Jewish service was going to start 15 minutes later and some folks had started arriving. (The FOD party was late afternoon in Skywalkers.)
We ended up going on an excursion with one couple we met at the party. Something we had booked earlier and told them about.
