Just a couple of words of advice:
- book your return shuttle on the day you arrive in town or at least 48 hours beforehand. I was a little surprised to find out that they actually don't have enough shuttle services www.airportshuttleneworleans.com
- take advantage of the street cars - a great way to explore the city
- I booked my hotel after visiting www.tripadvisor.com/ - great comments about hotels and other accommodations on the site; you sometimes have to read between the lines and right now it has worked for me in Chicago, New Orleans and Palm Springs.
