Walk/Bike, New Orleans

I think the best thing to do would be to park somewhere outside of Bourbon Street and walk over. Part of what ruined this experience was trying to drive through a crowd of people.
Definitely opt for walking up and down Bourbon Street.
There are even parts that you are not allowed to drive through.

Expect to walk! If you are visiting the French Quarter, everything is very close, but bring comfortable walking shoes. You'll definitley be doing a lot of walking! You can take a taxi or a shuttle from the airport to your lodging accomodation. Prices are a little cheaper for the shuttle, but it may take longer to get to the hotel as more than likely there will be other passengers to drop off.

Having a rental car and staying in the French Quarter did not work out well for me. I walked and biked for my site seeing and never did use the rental. The cost for parking your car is steep at the hotels.
I rented a bike from Michael's Bicycle at 618 Frenchmen St. (504) 945-9505 and it worked out great for me.

either car or plane...you will definately know what a swamp is if you drive there.
get around by WALKING. Don't drive drunk, please. You really only want to go to the french quarter, new orleans really isn't that great a city outside of the drunk quarter, I meant french, sorry.
