You can use your points for conceirge suites. We sailed on the Wonder last December in a category 3 suite. We booked it with cash, but I called a few months out to see if we could use points to cover some of the cost and they said no problem. You can break it up too, 1 fare with points, 1 with cash if you want. We were just looking to free up some cash for spending money by using points for one of the 4 people in the cabin. I forget how many points it was, I don't think I would ever book the whole cabin on points, but it is a nice option to have if you are short on cash up front.
