While you are in New Orleans, here are some recommended things to do.

Aquarium
Audubon Zoo 
D Day World War 2 Museum
French Quarter (Bourbon Street)
Insectarium

Luckily, we have a Rhein Main couple that lives just outside of New Orleans and will be assisting.

I can guide on the best restaurants.
**Look at October or November when the Saints are not in town to get the costs down.
I can recommend the best hotels close to the French Quarter.
