Best Option for Visitors?

I am coming in from out of town for a few days and don't know the Austin hobby scene. For an out of towner without referals, is the best option? An agency? If so, any recommendations for outcall to a nice downtown hotel? I don't have a lot of free time (or references), so I want to get it right the first time!

I am willing to post reviews though.

Here is a thread that includes those that are newbie friendly....
