We just stayed at Banana Beach and had an oceanfront on the top floor, but not one of the deluxe corner units. I wouldn't spend the extra money for a corner unit. The only thing that's really "special" is that you get windows on the side of your balcony and bedroom. These windows only look out onto Mata Rocks to the south, and a resort under construction to the north, so it's not worth the upgrade IMHO.

There's plenty of balcony privacy with all the oceanfront units, at least on the 2nd and 3rd floors. I would not want a ground floor unit.
