I'm surprised that no one has answered you as there are several reviews by people here that have been on the Coral already. We are thinking about doing a cruise on the Coral this fall, so I have done some reading about it. Seems like the balconies are various sizes with the "bump outs" often reducing the size on the ends but affording a great view. Personally, I would choose the mini-suite for the much nicer bathroom, more closet space, and much larger room. I love my balcony, but probably love the extra room size more.
I have about 3 pages of a discussion held on another board about sizes of rooms, covered balconies, etc. if you'd like to e-mail me (maryann@cruise-addicts.com), I'll copy it for you. Or maybe posting this will get some attention from someone who has been on it.
