Head out to the tennis courts with the kids on Saturday, because they’ll be playing for free.

The Tennis Club of Eau Palm Beach Resort and Spa is teaming up with the United States Tennis Association for Nickelodeon’s 10th annual Worldwide Day of Play. The event, held Sept. 28 from 9 a.m. to 12 p.m., encourages kids to get up and be active for National Childhood Obesity Awareness Month.

Children ages 5-12 can participate in tennis games all morning with the chance to win prizes. To find out more, call Karen Rembert, Eu Palm’s tennis instructor, at 561/540-4993.
