It is recommended that you sign up before showing up so that there are at least 4 or more people per court to play! We want to ensure a full court so that no one has to wait for a game. Additionally, signing up in advance makes it easy to prepay the $5 fee. However, drop-ins are always welcome! If you need to cancel or change the date after you signed up; please email firstname.lastname@example.org. We have a 48 hour cancellation policy.
