On top of the recommendation to spend a couple of days (3 works better-2 in
the French Quarter in cluding the Cabildo on Jackson Square and the
cemeteries and of course beignets and cafe au lait across from the Square,1
University/Uptown/Garden District) ,1 day to see Oak Alley and "San
Francisco" plantations and then 3 days in Cajun Country
(Lafayette,Opelousas,New Iberia) and then on to Natchez,MS;be sure to visit
Longwood.
I've lived all over the world and now am in N.O. and consider it America's
most interesting city
