Looking at the field guide, it looks like high floors and not a ton of rooms. I think the ", ocean view" category is counting anything that has a sliver of a view or even just a view from the balcony and not the room. I stayed in an ocean view studio many years ago and it was truly a very loud pool view room with a tiny bit of ocean off in the distance.
The only reason I booked an ocean view this time is because it was the only room available when I booked. If it wasn't on borrowed points 6 weeks from the end of my use year, I would have played the slots to get a different room. Alas, these points would be toast if I downgraded the view.
