We had terrible waves on the last night of our cruise. We were told not to step outside on the deck lest we get blown overboard. The crew laid out Chinese take-out containers every 10 feet or so along the hallway because so many people got seasick. There were hardly any people in the dining room, but we tried to eat something. Unfortunately, lamb is one of the least appealing things to eat when you are seasick.
On our next cruise, we made sure we packed the Dramamine.
