Starwood Preferred Guest - Best NYC property to spend a free weekend

I am considering using the AS mile promo and going to DCA, and taking a train to NY and use the free weekend promo. What would be the best place to stay. I plan to stay do a little shopping, and relax..

Thanks

Please disregard this last post, after getting excited and planning this trip, I realized that AS does not include DCA in the promo.. But if anyone has input on where to go and Stay with the AS promo. Places are canada, AK, CA, NV, AR. Basicaly all the West coast places. I want to get far from SFO as I can though.
