We love the World War II Museum. They are constantly expanding and adding new stuff. I think it consists of 5 buildings right now. Even if you are not a history buff, it's still worth going just to see the "Beyond All Boundaries" movie. My son has to see this each time we go to New Orleans. It's very interactive with the seats shaking, smoke, snow, burning oil smell, kamikaze strikes, etc.
I could stay there all day, as they have canteen live shows and other things going on. There are also veteran volunteers there sometimes. It's worth your time to be able to talk to the greatest generation who are just about gone.
The National WWII Museum | New Orleans: VISIT: Beyond All Boundaries
I was looking at a map and the campground is just northwest of the French Quarter per se.
We usually stay in a hotel on Carondelet, which is just right across Canal Street from Bourbon Street. I highly suggest using the streetcars when available and are on a route you may be partaking. These routes will be on the South, East and somewhat West end of the French Quarter.
You can actually get day passes which allow you unlimited access to all the streetcars and/or buses in New Orleans, which cost $3 per day per person. I usually order a 3 day jazzy pass online ($9) and have them shipped to my house. They only activate and the clock starts the first time you use them either on a streetcar or bus (the machine that takes your money also takes the pass you have). It's a lot easier to keep up with these passes than keeping exact change $1.25, each time you get on one.
You can download apps for you phone that let's you see where streetcars/buses are and also you can text a number at each each stop that will text you back the next time of expected arrival. If on Canal street, there are three streetcar lines intersecting and you can use any of them to go up and down it. You can travel to the south end of Canal (at the MS River) and then get on the Riverfront line and go to Jackson Square. Here is a site for that. I would recommend just looking at the maps/routes of everything. Once you kinda learn the routes, you can judge which ones you need to get where.
You can use the St. Charles streetcar line to to get you to within one block of the WW II Museum (get off at Lee Circle)

Also at the southeast end of Canal, there is a ferry that crosses the MS River over into Algiers Point. This is fun to take and there are some things over there in the second oldest neighborhood in New Orleans.
There have been other great suggestions for things to do, and walking the French Quarter is the best way to see it all. Everything is within walking distance if you have the time (an Old Steven Wright joke). Take time at Jackson Square to watch all the street performers and artists. As also stated the food, is fantastic. My daughter insists we eat at Pat O'Brians when we go down there. She loves their shrimp and grits and their famous hurricanes. She also loves eating in their open courtyard, especially at night with their fountain and such.

Are you going to have children on this trip, or is it adults only. I can offer more suggestions depending on the audience.
