I enjoy the stage performances - and even though the "Princess Dancers" (and their equivalents) have become a bit homogenous/a bit corporate - I still get a kick out of live acts. I don't think I'd be willing to pay extra for it - but I wonder if the cruise lines are missing a trick by not providing "back stage access" to the performing troupes? Maybe a few "first come first served" cocktail gatherings with the "stars?" Maybe a few "behind the scenes" get togethers with the performing artists?
