I can't imagine anything worse than being a passenger on one of those (other than begin a low paid crew member who's been forced to remain aboard for the past 8 months)
Yes. I got dragged on one by my parents in the 1980s. I wanted to kill myself after about a day. It was like butlins with no escape and even lower standards of hygiene. It’s a profitable captive market to milk a load of people drowning their sorrows in alcohol and feed the slop in return. Why you’d pay for it I don’t understand.
Secondarily, good riddance to the whole industry.
Edit: after reflecting on this I don’t think my parents enjoyed it either. They went on it because it was the done thing at the time and they could tell everyone they went on it.
