Six of us went to this cruise leaving NYC to FL and Bahamas. Booked it 3 months prior, not sure if we got the best rate, but this week's rate is quite reasonable for a mini-suite so we splurged on one, with my in-laws across in an interior cabin.
Husband and I have been seasoned cruiser, bringing along our 4 yrs old and 20mo old daughters. This is what i recalled for our cruise.
Positive:
11578 was located in the mid section, close to the elevators but not right out there. I was happy with the location. bigger balcony, and it is not exposed. However, it does get a bit of noise during kids club hour, as it is right underneath it.
