We (2 guys, early 60's) have been on 15+ cruises on NCL and we have met many, many wonderful people through these meetups. Both men and women, almost always couples, from all over the world. While they have mostly skewed older (over 40), there have also been some younger folks. This may be because we tend to choose longer itineraries. On some sailings, we have become fast friends with just one other couple on board, while other times there has been a large, gregarious group. Give it a try the first couple nights, as sometimes people don't make it on embarkation day. We have also found that once you meet others, you can adjust the meetup time and place to suit your needs. Don't miss out on the chance to meet some really great people!
