There are no promenade view balconies. Do you mean the Boardwalk?
All the inside balcony cabins have shortcomings in my opinion. Zero privacy is the common issue. Central Park balconies are reported as being hotter with less air movement, plus you do get noise from both below and above. Boardwalk balconies really have noise issues. You have the constant carousel music, plus activities at the AquaTheater which also happen during the day. And don't forget the zip line and flow riders are right above.
