Led by Citiparks Tennis Program coaches, players ages 4 and up can control the racquet and the ball in a few minutes and get a game in on their very first day on the "court". The mini-court and small net are also kid-sized as well as fun for all ages. Free activity takes just 4-5 minutes to enjoy. Walk-in. Each group of 4-6 players plays 4-5 minutes. And yea, it's ok to come back later and play again after seeing another show!
