Speaking from second-hand information/advice only, I'd Like to add a caution to a previous response. I'd suggest you check on the particulars of the individual ship invovled. Yes, they all are suppose to have dancing, as the previous respondant indicated. But don't just go on that -- I'm told room size, number of rooms, diversity of music, times available, and other features vary greatly, even within ships of the same "line." You might try contacting the lines themselves to see what info is available about specific ships, once you've made the "destination" choice?
