My heroine is going on a fictional cruise ship, so I can make up quite a bit since I've never been on one, but there's one question I can't seem to figure out through my online reading from different cruise lines. Which deck do passengers board on? I would imagine it's the main deck, but I'm not sure. Can someone help me out? Which deck and if y'all can remember, give me a general idea what it looks like so I can fine tune it to fit what I have in mind for my story. I would greatly appreciate the help.
