I have 164 BW points which are quite valuable - it is now more than 7 months so you may be able to get a standard view room at BW for a LOT less points than a preferred BW or any room at BC. For instance, you could get a standard 1 BR at BW for 174 a week and it would cost you 214 for a preffered 1 BR at BW or BC.
Let me know if you still need the points.
