If you're looking for a "different" resort from BWI, you couldn't get much more different. Wild animals outside your window, exotic food, a fire pit to sit around in the evenings, an amazing collection of african art, and wonderful CMs with stories to tell. We really love this place.
The Poly might be a good choice also, right on the monorail, sit on the beach and watch the fireworks/EWP at night. Tiki-lit moonlight walks. Tonga Toast and Kona Coffee for breakfast.
Or WL, another "get away from the bustle" experience, with a stunning lobby, boat ride to MK, and wonderful food at Artist Point.
