I agree with the above posts, but would also add, consider the time of year you are going. The WL is wonderful in cooler weather, because there are several places where you can sit in front of a roaring fire. Fiancee and I were there on a cold, rainy, weekend and we had the BEST time hanging out at the hotel, sitting in a little nook, in front of the fire. Even my fiancee (who up until that trip only went to Disney to make me happy) said it was the best trip we had ever had. He is now sold on Disney!!
I would also add to the suggestion list, Port Orleans Riverside, the Magnolia Bend area. This is the area with the southern mansions, and if your wife is the type that appreciates that old-style romance, this is a great choice.
