No, but downtown is a free Chademo charger which works great. Depending on when you go, you might get the adapter if is available before. I will be down there next week....
There are now two 80 Amp HPWC chargers at the Best Western La Place Inn (about 30 miles from downtown NOLA). Guests only, unfortunately.
Plugshare also shows a residential 14-50 available upon request, as well as Solar Alternatives, but they might have 6-50 instead. Check plugshare.com for details (registration required for access to residential details).
