Med Center – Spots to work remote from?

I'm headed into town for some appointments at MD Anderson (#funtimes). My appointment is tomorrow @ 2:30 PM, but I need to check out of my hotel by 11 AM.

Are there any decent spots in the Med Center to hang out for a few hours and get some work done? I haven't lived in Houston or inside the Loop in a million years – I know I could hang out in the hotel lobby, try the free WiFi @ MD Anderson, or head to the WeWork downtown (I would rather not have to hassle with parking downtown)…

Ideas are very much appreciated!
