We went on a night cruise & there was a sign saying 4 ft waves & rough. My sister & I took 2 Dramamine thinking we would be ok. We ate the buffet while waiting & it was alright but definitely not worth what we paid. It's hard to walk once out in the water if it's wavy. Despite the dramamine I really hated the waves. I found it hard to walk without hanging on & felt nauseous but made it without running to the bathroom, however my sister did not & made several trips there, & in between sat with her head on a table, as did several other people. I found it helped to rest my chin on my arm on the machine I was playing & not look around too much. We were staying in Myrtle Beach & everywhere we went we were so happy with the friendliness of people there, but of everywhere we went (restaurants, stores, gas stations, hotel), the people on the boat were probably the least friendly. They weren't nasty, just not overly friendly...like they were just there to do their job & not talk to you.
