We stayed in 8048 on a 4 day Wonder cruise. The cabin was absolutely beautiful and quite large. The concierge service was ok, but not as good as others here on the cruise board have reported. Our only complaint was the noise from deck 9. Chairs and tables being moved around early in the morning (4:30 - 5:00am) and the deck party that went very late.
Our next cruise is booked in a cat 4 under the hair salon to try and get some quiet. I would not book one of the cat 3 cabins again, because of the noise.
