If you're in the Twin Cities area (guessing based on your Twins logo avatar and your location listing of "Midwest"), check out Stock & Barrel in Chanhassen - they run indoor matches in the winter for $15 in what they call a "shoot and scoot" format. It's rolling signup per-stage, so you show up, put your name on the sheet, and you're probably shooting within 10-15 minutes, rinse and repeat for the second stage on the other bay, and then you can leave immediately if you choose. Indoors with only 2 bays means it's somewhat limited, but it's at least a miniature version of what you're asking for.
