Away from the parking lot and water park make a playground with tables and sun shade. Mothers and the kids want to come and hang with DH Dad but have nothing to do. In my case my wife also rides and we could take turns at a base camp playground while the other gets in a few runs. The folks spending $$ at your spot are mostly those with families. What better way to introduce kids to the scene and sport. Plant the Diablo seed early. Not to mention this relieves alot of the "when are you gonna be back home" stress because now its a family day.
