Keep in mind that your balcony faces the one directly across from you; very little to no privacy. Most folks in these cabins end up keeping there shades drawn for a large portion of time for this reason. Depending on the cost; I'd recommend an ocean facing balcony to really the use and experience.
However, if it's a choice between inside and inside balcony - the inside balcony at least gives you some additional space and a view. Just wouldn't expect the same privacy as provided through the ocean facing balconies.
