We stayed on the top floor of bldg. 13 and we had a partial ocean view. We were facing the pool. I wouldn't waste your money upgrading. The room is only a little bigger. We had a king size bed. It was a nice room, but the view might be gone. We were there two weeks after Hurricane Emily and most of the big trees were either gone or stripped of their leaves.
Here's a pic of the view:<a href="http://www.picturetrail.com/gallery/view?p=10&imgid=109214930" target="_blank"><img src="http://pic20.picturetrail.com/VOL169/1058178/8194380/t-109214930.jpg" border="0" alt="Free Image Hosting at www.picturetrail.com" /></a> Click to enlarge.
