Here is some information from the Nepean Sportplex administration:

Now that the entrance and lobby are closed for renovations, we are asking all clubs to exit no later than 15 minutes after their booking end time.  The luxury of waiting in the lobby for a ride home is no longer an option.  Therefore, all parents should be at the Sportsplex ready to drive their child(ren) home as soon as your club’s practice is done. Coaches or a club representative should assist in clearing the change rooms to ensure all athletes are out before the facility is locked and closed for the evening.
