Where ever you choose to stay your will be dealing with stop and go rush hour traffic on all expressway routes, in the morning and evening, so depending on the times you need to be in town plan enough time for the nightmare commute. As for the campgrounds I have stayed at Yogi Bear on Music Valley Drive and it has pull thrus and is well suited for big rigs. Spacing between sites is not generous but there is enough so you don't feel like you're in someone else's trailer. I like it there. Close enough to Opry Land Mall for the wife and quiet enough to just hang out if she prefers. Lots of good food in town so take her out a few times and enjoy what Nashville has to offer. Great town.
