We'll be at the Club Quaters Central Loop. Turns out it's not as close as I was lead to believe by my better half. It's at W Adams and S Clark. A few blocks away, but still in walking distance to the park.
I was also off on the price, $129/night. Their site says it's a private hotel and you must be a member, but I got the reservation through Orbitz. A few more rules to follow with Orbitz, but it's booked and reasonably priced for the area.
