Good info from MardiGrasNewOrleans.com (full story):
Whether you’re enjoying daiquiris or locally brewed beers or even just water, eventually you’re going to need to use a restroom. For those of you that live close to the parade routes, you have my envy.
For the rest of us, here’s the guide to navigating the bathroom crisis during Mardi Gras season.
Do Not Urinate In Public
Something like 90% of the arrests made along the parade routes and in the French Quarter during the parade season are related to people peeing in public. So don’t do it, there’s a good chance that you’ll be arrested…not to mention that it’s plain ol’ rude and not very lady or gentlemen like.
Portable Public Restrooms
There will be a limited number of porta potty’s along the parade routes. A very limited number, especially when you consider the size of the crowds. The best bet are the portable public bathrooms set up around Lafayette Square near the corner of St. Charles Avenue and Poydras Street.
