I would go with the CBR preferred room. We just did a POR Royal Room, bringing my nephew to Disney for the first time this past November. The room is pretty much on par with everything else in the moderate class with prince/princess theming and a headboard that has a button-activated fireworks light show. It was a bit far from the main building too. For my wife and I, it wasn't really worth the price differential from a regular room. CBR will likely be more crowded, but the room closer to the action may be more desirable.
