Missouri Athletic Club was an okay experience. Not too bad, not too stellar. My conference was at the America's Center couple blocks down the street so the walking distance was great, but not a lot of eatery around the hotel. The hotel room was okay at best - the room had one of those doors that connected to the room next door and holy cow, it was anti-soundproof, I could hear EVERYTHING. There is also a dress code which is old school. The fitness center is awesome though, for $15 and if you stay multiple days, it's worth it.
