ISO Open Mat/MMA Gym drop in during the work week

Hey yall, I was wondering if anyone knows of an open mat or gym I could drop in during the work week to get an extra day in that is inside the 610 loop. I already train 2x a week and want to squeeze 1-2 more day in but my coach and I have scheduling issues. Weekends are jam packed for me otherwise I would go to Renzos in Sugarland on Sunday morning for their open mat. I tried out a gym close to my place but drop in do not fly so any help would be appreciated. Thanks in advanced!
