I agree that bigger does not mean better. I also considered the open promenade design of the RCI ships to be an incredible waste of space. While it makes the ship's size bigger, it does not in itself provide anything other than open space.
I'd rather go to smaller ports and experience local culture than only go to the large established ports that the mega ships can dock at.
