You get on the boat, have your picture taken and sail out into the ocean. After you sail for a while they bring you drinks and then you have dinner. While you eat, there is entertainment. It's very beautiful sailing on the ocean at night. One of our daughters got seasick, so it might be a good idea to take a Dramamine before you get on the boat. This dinner cruise wasn't as nice as the one we took in Oahu, but it was still nice.
For this particular cruise we were suppose to be at Lahaina Harbor at 4:30pm. When we got there, the people in charge weren't there and didn't get there until 5:00pm, then we waited until 5:30pm before we were able to get on the boat. If I was to do it again, I think I would choose a different dinner cruise. There were many dinner cruises leaving from this port and many were in nicer boats with better food and entertainment.
