Recently I organized our Roll Call's M & M onboard the Pearl for the September 30, sailing.
I contacted NCL by email 6 weeks before the sailing date and asked to have a meeting on our first Sea Day (was supposed to be ONLY Sea Day but Hurricane Fiona changed that for us). We had approximately 50 Roll Callers RSVP and almost 60 showed up.
