Absolutely, positively, do not miss the Preservation Hall Jazz Band. Preservation Hall is in the French Quarter and has shows nightly if I recall correctly. They are inexpensive (tickets were around $5 to $7 or so), the building is a bit run down, sometimes it gets crowded, but you will hear the best jazz music you have ever heard in your life. It will bring a tear to your eye and send chills up your spine at how pure and good the music is. A riverboat tour can make for a fun afternoon. I think we took a trip on the Natchez and it stopped at some civil war battlefields and we saw some mansions. Have a great trip.
