The room categories at CBR are confusing, IMO. When I stayed there in '06, I booked a Water View room and paid a preferred price. I read on the DIS that I should have booked a "Preferred" room. I called WDW to confirm, and the CM told me I would probably have a pool view. I was so upset b/c I wanted a lake view.
When I checked in (at 1 AM!!!!) i talked to the CM about desiring a lake view. It had already been assigned to me! We stayed in Trinidad North, Building 31, corner room, 2 windows, beautiful view. We didn't actually see the view until we woke up the next morning and we were so HAPPY!!!
I would book a Water View, make sure you pay the preferred rate, and have it noted on your reservation that you want a lake view.
