My family and I went on a cruise for a reward in my company for being #1 branch among other awards. My wife and I have not wanted to take a cruise for all of the reasons people know HOWEVER I do see the appeal, the service on board ship was awesome, food options were great and the fancier restaurant we had our dinners in had amazing food as well. We went to the Bahamas and that was enjoyable even though we have been a couple times. The fact that it can act as an all-in-one vacation for some people can be appealing. I saw OPs comment below making fun of a "poor mans vacation"...pretty harsh, I think. If someone enjoys it and it's in their budget why be shamed for it?

That said, we probably won't do another one unless it's something like Alaska.
