I would pay a few hundred a month (or more?) if I could hold semi-private events for 20-30 people occasionally in the evenings, but the listed hours of 9AM-5PM

I would pay a few hundred a month (or more?) if I could hold semi-private events for 20-30 people occasionally in the evenings, but the listed hours of 9AM-5PM are uninteresting to me. Mechanics Institute still sounds neat, I'll check it out sometime. Thanks.
