"Guarantee" balcony epic

hi all,

My husband and I decided to rebook our feb 2018 cruise to a balcony rather than inside cabin. We chose the "BF" category but since apparently there wer less than 8 cabins left it was considered "guarantee status" but not BX category. We still got UBP, UDP, and no port fees/taxes so we got a good deal. The next category up would be like 100 extra pp and now the tax free promotion is over. anyway, we don't really care WHERE our cabin is but we recently discovered the "hull" balconies which seems like more of an ocean view. Are there pictures of the hull balcony anywhere? I found one lengthy post about it that included pictures however the pictures have been taken down. Also, are there any other "problem" balconies we should be aware of? I heard of one that is uncovered and apparently everyone above you would be able to see you? Not sure how I feel about that either.
