I've never gone on a quilting cruise as they do seem to be quite expensive but I have gone on a regular 7 day cruise on a Carnival ship. It was absolutely lovely and I hope to take another one next year. The cruise I was on seemed to be very family oriented with lots of children. I didn't see any drunks or bad behaviour so maybe it depends on which ones you take or maybe we were just fortunate? I can't compare to other cruise lines but I know Carnival has wonderful bargain rates and a group of people could arrange their own private quilting cruise for less money if they wanted to.
