While I've not experienced this ship, I have stayed in both an aft and a corner aft. The corner aft typically has a larger balcony. When you say aft, is it truly at the very back of the ship? If so, IMHO, I could not justify $300 more for the corner. I guess it depends on how much time you spend on your balcony.
