I am not quite sure what you point is: there are the usual free options like most ships. As Shoreguy said, the extra charge dining isn't any different than any other line, there are just many more options.
At first I wasn't sure if we would cruise the Epic, but now I really want to give her a shot. Because seems pretty contempory we probably will only do it once, we like a certain amout of tradition and yet I feel this will be the tread of most of the new ships coming out in the next 5 years. Certainly if she is successful other lines will follow.
