Our 10th anniversary is this week, and I'm thinking of booking a trip to Nashville as a gift to DK. We'd be going in early December for a hockey game (Flyers vs Preds). Likely would have full day Saturday, Sunday morning/afternoon, and most of Monday free. (Would leave Friday evening and take a later flight out on Monday). 
Activities would need to be kid-friendly, since we'll have Wolverine with us (she'll be 6 by then.) 
Trip would be a surprise (I know he can cover the vacation day on Monday), and Wolverine would miss 1 day of school (kinder - which doesn't seem like a big deal). 
I've only flown through Nashville, so recommendations on things to do and places to eat would be appreciated. Would like to plan one dinner that's a little nicer - Wolverine knows how to behave in restaurants, and isn't a picky eater, so no worries there.
