Tristar: You could try the Metrolink-Fairview Heights stop. It's on the Illinois side not too far from the I-255/I-64 interchange, but I don't know how close it is to where you're staying. Its address is: 9200 St. Clair Ave - Fairview Heights, IL 62208. I stayed on the Illinois side before and used the Metrolink from there to get back and forth from the Convention Center, which is two stops away from Busch. The ride wasn't terribly long. Nothing seemed questionable. There was a nice, big parking lot. And it seemed safe, even when getting back late at night. Maybe someone else from the STL area has another idea, but that's my best guess based on previous experiences and having relatives down there.
