If you are bankrolling this trip yourself, have you checked Priceline? I would guess that they would have a zone guaranteeing you something within a mile or two of Union Station.
When I was in STL on business, we stayed at the Marriott. Nice place, good location for everything. But I wouldn't pay their rates with my own money or anything.
