HI!
I have been to the "ICE" at Gaylord Opryland in Nashville, Tn. It is very nice but be warned it is really really cold in there! They have tons of beautiful ice sculptures and one huge ice slide that you can go down. It takes maybe 45 minutes to go through. They do provide you with Parkas but I would strongly recommend taking gloves, ear muffs, hats. I think you will enjoy it.
