OS 7330 is a bigger than average sized room. IMHO it is not a suite as it is just one big room. Mid ship location with slightly larger balcony. Nice bathroom with full tub shower. Sound on TV does not work well even after having service twice during the cruise. Read entire member review.
Cabin was great. Ocean Suite. Starboard side, so of course on one leg of the journey we didn't get sun most of the day. Roomy balcony, very nice furniture. Two chairs that reclined, one other chair and a small table. Roomy cabin--great bed with a sofa and chair. Plenty of storage. Dressing area just outside the bathroom was nice. Very nice bathroom. Double sinks and great jacuzzi tub with shower, and sliding glass doors. Suite came with VIP status which was particularly important during Embarkation. A little too near the front of the ship...next time would try to be more mid-ship, but it's not a huge thing, just preference. Quiet (except for the first night when the kids across the hall were partying). Read entire member review.
We spent a lot of money on this cruise even paying extra for an ocean suite which was a nice suite, but you could see the wear and tear on it. The bathroom however, was very nice. I would recommend an Ocean Suite but aboard another cruise line and not with Carnival!
