AMEX travel agencies have negotiated corporate rates at a number of lower Manhattan hotels: Fulton Plaza $170 standard, $255 superior; and Holiday Inn Manhattan Wall Street, $191 are the two nearest Wall Street. They also have a few hotels in the Chinatown/SOHO areas. Call or visit any American Express Travel Agency (you don't need to be an AMEX cardmember). Ask for the "Select Rate" if they don't come up with these rates.
