Who here has been on a cruise?

I’m not afraid of traveling, in fact, I love it. But when it comes to planning, I’m absolutely terrible. I keep thinking about going on a cruise because other than choosing the destination, I don’t really have to worry about planning. Sometimes I hear stories about cruises and it sounds more like a zoo though. Other times, it sounds a little claustrophobic. People who have been on cruises, what’s your opinion? What do/don’t you recommend? I’m all ears!
