I found no specific cabin # reviews however, same category reviews in same area of ship would apply on Dream and Fantasy.

You are over the kids clubs sort of, shouldn't be an issue. You will have the outer skin material on the forward side of your balcony. Some like it, some don't. You will be sailing forward as you sleep, but that puts the couch on the aft side of stateroom, therefore if seated at couch, the outer skin may interfere somewhat with the forward outside view, more so than if reversed. It is not that big of deal. Just trying to give you the scoop.
You are basically directly over the lifeboats, however you are between them, which also concurs with this outer skin on the outside part of the balcony. The nice attribute about said location is you are between lifeboats and potentially have one of the rare views down the the sea , albeit slightly disrupted. I would keep said cabin if OK with attached photo. The outer skin in your case IMO is worth it in this case, due to possible view between lifeboats.
The outer skin on your balcony is not in place in this photo fwiw, but.... the outer skin directly above your deck is in place when said photo was taken. So do notice what said skin is and how it feels and tastes to you before you decide to change said booking.
Search other complete build photos for full skin observation.
One obvious advantage to this cabin is, if the need occurs to muster, you can just jump down to a lifeboat.
