People seem to like going on cruises since it is apparently a rapidly growing business, despite some recent horror stories of norovirus outbreaks on the boats. From what I can tell from the advertisements, these things are a floating combination of hotels and amusement parks. But in the latest episode of his show Patriot Act, Hasan Minhaj says that underneath all the gaiety and laughter, the business model of these companies is based on ruthless exploitation of labor, dumping of waste into the environment, and a massive amount of greenhouse gas emissions, combined with careful avoidance of any responsibility for anything that might go wrong on board, including sexual assault.
Given my slightly introverted nature, I think I would not find cruises enjoyable. Being constantly surrounded by large numbers of people who are determined to have a good time 24/7 and get the maximum benefit from the limited time on board would wear me out pretty quickly. I would likely retreat to my cabin for long periods of time, which would defeat the purpose of going on a cruise.
