I would be flexible/understanding if I were in your shoes since the D+ BOGO is only valid for the first two nights of the cruise per RCI’s rules. 

That is correct “per the rules” but once they have accepted/reserved an alternative I think there is an expectation that they will honor it, or at least inform you if it is changed/cancelled.
