"If you're flying on the 2nd, it's 317 dollars from Metro to New Orleans. From State Stree to Bourbon Street is 1,052 miles. Google Maps shows no tolls. My math me burning 59 gals of gas each way (plus incident gas driving around town. Although I'll be most drunk and taking mass transit/cabs). So that's 235 on gas (assuming an average of 3.99 since I have to feed my V8 premium). Three of my passengers (not my wife) will likely toss in 50 each for gas per trip. So I'm paying 85 on each leg of the trip. That leaves me with 230 or so each way to cover wear and tear. So I'm saving enough to buy 2 new tires, so that's a decent amount saved. Also assuming my wife spends nothing on transit she had a savings of 647 dollars by not buying any airline tickets. So as a unit we save 1/38th of what my car cost new in exchange for using 1/50th of the warrant (100k warrant). Not a bad deal.
If you do the trip in a normal car instead of a 420 HP midlife crisis sedan the savings are even greater since you burn less gas and regular is cheaper.
Google Maps shows no tolls on the route I found."
