I’m going to be on this cruise in June, also. If you have never been to Nashville, arrive a day or two early or stay after the cruise if it ends there as there are many things to see and do. I’m happy to offer suggestions if you’ve never been as I visit family there a few times each year. There is a complementary excursion offered to the Opry, so definitely sign up for that.
Does your cruise start or end in Nashville?
