Sports Complex Question

Hey all-

Was wondering about the Sports Complex near Sajik to any and all with experience there. Does the gym (indoor gymnasium or the gymnastics gym) allow for groups or individuals to go to their facilities and use it as free space? (ie can I and a few friends go and use the space for some martial arts practice? Yes, we can go to an actual dojang, except that every dojang that I or anyone I know have been to only allows their space to be used for folks who attend their classes. And no, I'm not interested in taking classes)

Thanks!
