We once had a meet and greet on the Epic in which a lot signed up and very few, actually only two tables worth showed up, plus a few NVL officers. The person who set up the meet and greet was actually one of the ones who did NOT show up. It was embarrassing.
One table had I think it was 6 who had signed up to do shore excursions together and needed to meet to figure out where to meet for the excursions. There were 4 of us at the other table. The other husband at the table recognized that I was the one who had said his DW was an art teacher. He quizzed her about what to see in Florence. She, of course, was happy to discuss art.
