A few years ago a local squash club went out of business and the premises were acquired by a golf business. The two courts were converted into simulators, the bar was upgraded and a gym built. I had (have) lessons there in the winter. The business didn't really catch on. And, as Jason notes, whenever I was there, any groups using the simulator as a social event, rather than for practice/teaching were not "youth". Sadly, the footfall didn't justify the bar, etc., and whilst the simulators remain there (and I still get lessons there in winter), I think it's fair to say that it hasn't succeeded.
