The airport has several free kid-friendly (and unsupervised) areas, so find the one that best suits your needs. Both the Children’s Playrooms and Kids’ Parks are ideal for toddlers, with large play areas cushioned with foam; for a slightly older crowd, the Kids’ Rooms have mini jungle gyms with a small slide; and Nurseries are enclosed spaces with cribs for infants.
