I'd pay $100, just for a track day to happen for CR, the number of people doesn't really matter in my experience. When I ran track days, whether it was 50 or 100 people, after the first hour, the crowd really thins out and unlimited runs was possible. The only real stress point was someone breaking down and closing the track for some time, but I was lucky because that to never happened.
The bigger limitation to the number runs I was getting was my own vehicle prep in between runs like checking the data logs and modding the tune, swapping out plugs, letting the car (intercooler, clutch, etc) cool down.
