Cecilia – thanks for the question. Here is an answer to help you, provided by Rick Butler, a long time JVA Club Director from Sports Performance Volleyball in Chicago, IL

"40-45 parking spots for every competition court is a solid number. We have 500 spots plus street parking for 12 courts and there are times that we get very crowded. So 120-140 spots if the facility plans on hosting events."

Hope this helps!
