ShakerLady, I have been on both ships. Cat. D on the Grandeur and 3 Cat C's on the Vision. We had both sides (corners) on the Vision. They were wonderful, the balconies are huge and wrap around to the side. There is NO noise, as far as I'm concerned, there is no better room then the 2 corners, Cat. C, on the Vision. Book it if you can get it. You won't be dissapointed.
