Cruise life can be VERY social, it's pretty much up to yourself. The crew are mostly very tolerant and liberal as there are so many different people, cultures, nations, sexual orientations to deal with, so it isn't much room for so called moralists
You'll soon find out if this is a life for you or not. I loved it. It's been four years since I left NCL, and not a day goes by without thinking about memories from that time.
