"There are actually 6 outdoor/hardcourts at this facility, 4 of which have lights for evening/night play. All outdoor courts are in good condition. Although I've never been inside the indoor facility, the bubble looks large enought to hold 4 courts. Play is on a first come, first serve basis. However facility staff/pros do schedule courts for clinics and matches. Also the MD Department of Parks and Recreation do have signs posted governing the hours of operation for both the courts and the park. I'll provide more information at a later date."
