well you see from the airport the cabbys drive vans around and do they ever drive MAD... 80 miles an hour in a 30 mile zone.... so go at your own risk... I did they were kinda fun but my mom almost had a heart attack...
The historic portions of New Orleans are close to each other so the taxi service is fine and the public service bus. The most fun is the St. Charles Street Car.
I usually recommend the St. Charles Street Car line or United Cab to everyone.
We rented a car from the airport....which can be a pain if your hotel doesn't have parking available. There is next to no parking in the French Quarter!
I don't recommend a taxi, unless you're alone. If you're with a group, they charge the meter price, plus an extra dollar for each person over one. So, if your fare is 3.50, and you have 4 people in the car, you pay 6.50 (then a tip is expected too...so it's up to around 8.00-----not exactly a nice policy)! Walking is great in the French Quarter, and the trolley is available around most of the rest of the city for a lot less than a taxi.
If your flying , there are flat rate fares from the airport. ...$28
Forget the auto, there is no parking anywhere in the Quarter and the cab drivers are ruthless if they aren't on your side.
Safety can be a concern in New Orleans and it's not wise to walk in some parts of town at night. Fortunately, cabs are easily available in the French Quarter.
