Is this a Cat AA you're talking about? If it is, then it's a great deal!! We never sail w/out a balcony. Once you've had one, you may never want anything else. We enjoy the morning coffee and danish on the balcony as well as the late night snack.
We had the AA on Grandeur, Voyager and Explorer. They were wonderful. Very spacious w/ huge balconies. The cabins themselves are very spacious and does NOT feel overcrowed w/ four people.
