Carnival is our last choice for a cruise but we (and when I say "we" I mean "I") were so desperate to get away for a few days and since Norfolk is 20 minutes away we decided to go for it. I sweetened the pot by getting an aft vista view cabin #7440.
The Good:
THE CABIN: The cabin was great. It was probably the second best we had next to the handicapped one we had after my wife broke her foot.. It was laid out a little different and did not have a sofa but we didn't miss it.. The great thing about it was that there were two loungers and 4 chairs and a small table and still plenty of room. If you wanted sun or shade you simply just moved to the other side of the balcony because it wrapped around. There was some vibration but not enough to bother us and it really was quite lulling when going to sleep.
7440
Great vista view and worth the extra dollars. But know there is no sofa. The layout is the best we ever had. A little vibration but nothing major.
