We stayed in a balcony 2 years ago on AOS. My husband is very cheap, not frugal, cheap. He now says he will never stay in an inside room again after the balcony. We had breakfast and coffee on the balcony every morning.
We stayed in a suite last year on our Europe vacation and now he wants suites all the time. To me on this cruise the southern it is worth the extra money for a balcony. Depending on what catagory, 188 sq. ft to 210 sq ft. I think.
We had the smaller balcony stateroom on deck 8 and it was great. Ours was on the starboard side. In St. Maarten and St. Thomas, we faced the island and in Aruba and Curacao we faced the ocean. The rooms are nice, a bit small, but most cruise ship rooms are. The showers are tiny but that's also normal. You'll have a great time in your balcony room.

You are in for a treat. Be sure and order room service and eat on the balcony.
Sometimes breakfast before breakfast is nice on the balcony. Be sure your steward tells room service to call your cabin to wake you up 3 min before bringing your previously oredered breakfast.
Make sure you get a balcony on the 7th floor or higher and not on the 6th floor as the view on these balconys is not as good, due to a lot less glass than the higher floors. We were on the 7th floor (cabin 7638) aft just past the hump and it was a great cabin. I actually don't find the balcony rooms that small, there is a king size bed (they call it a queen but it's closer to a king size) and a 3 seater couch. And yes once you've had a balcony you probably won't go back and breakfast on the balcony is wonderful. I would suggest the starboard side of the ship as the view is better in St. Thomas and St. Maarten.
