I just went through a dilema such as this and got great feedback from the dwt family. My whole thing is, When are you going to travel to wdw for your anniversary??? I love the Contemp but right now i heard it is a mess because of all of the construction so that might factor into your decision. Also, does one resort have more sentimemnatl meaning than the other? I would factor these into your decision..
