1) Cheekwood Botanical Gardens, needs reservations I believe. May have changed, but not sure. 2) Adventure Science Center, really a great place for children of all ages including adults. 3) Centennial Park, it's a great place to walk and run around. I'm pretty sure there's a playground. Plus it's downtown off of West End near a bunch of great restaurants. Do take out and have a picnic next to the Parthenon! 4) Opryland Hotel, beautiful atrium and has a bunch of restaurants inside. But is also right next to Opry Mills Mall that includes the Aquarium Restaurant, Rainforest Café and many more great restaurants for kids. Also includes shopping for days.
