$200.00 for a Luxury hotel in New York? When were you there. l992?
Try the Westin Central Park South (the old Ritz Carlton) 500 miles in the airline program of your choice, plus Westin points as well. Hilton and Sheraton let you do the same thing as well (I think), but they are just an OK place to stay.

The Waldorf is good as well. (It's a Hilton)
