I was on the Norwegian Dawn 2 years ago in April. We had 35ft waves. Also i was on the Dawn this year and we had rough weather. The captian called "Open Bar" -free drinks. Did they call "open bar". For me even with giant waves i still had fun.
All i know is it docked where i live, Charleston SC. I should have drivin to the port and seen it. I know the wave went up to deck 10, knocked out some windows, and flooded 60 cabins. Some guests were flown home today from charleston. They got half back on this cruise, and half off of a future cruise.
