Question for the DVC add-on experts: I just received my add-on paperwork from Disney (same resort, same use year). I now have two versions of the Benefit Guide, POS booklets, etc. Is there any reason I need to keep the documents from 2010? (The new ones were revised in June or July 2012.) I dislike storing needless paperwork, so if there is no compelling reason to keep the 2010 versions, I will recycle them. Thanks in advance for your input.
