Any moms near Nashville, TN?

I will be in Nashville for the weekend. My husband will be working, so me and my 20 month old son are taking suggestions of things to do. Children's museums, fun play areas, ect.... I haven't been to the Opryland Hotel, anything he would like there? Does the Opry Mill Mall have alot?Any moms near Nashville, TN?
I live in Nashville! Opry Mills is the tourist spot definitely. It has a Merry Go Round in the center of the mall (food court) which is always booming with kids..there are a few other little kid rides throughout the mall and a train that will drive you around inside mainly designed for kids. Its really cute. The mall is always super busy, though, so if you don't mind a crowd I'd check it out. There's also a Disney store that we love to go to! The Opryland Hotel is really not kid oriented...its nice to walk around and look at everything b/c its sooo fancy, but thats about it. Your son might also like the Aquarium restaurant at Opry Mills..it feels and looks like you're eating underwater and the fish are beautiful. My 14 month old son loves it. We have a lot of nice parks and things but its really cold so I'm guessing you wouldn't want to do that. Enjoy your visit!
