Cat 6a (oceanview) is 185 sq ft. All cabins have two lower beds (covertable Queen)...w/either 2 uppers or 1 upper/1 lower or 1 upper and they'd put in a roll a way. These cabins are located on the Riviera deck. I hope this answers your question.
PS...I will be sailing on the ship August 5th, 2001. I am looking forward to it. We are in a 4b w/a roll-a-way.
My wife and I sailed the Inspiration last week and had a 6A oceanview cabin. It was plenty roomy for us. We heard several people comment that the cabins were generally bigger on this class of ship than on ships of other lines they had sailed in the past.
