There is a Hampton Inn on St. Charles Ave - in the Garden District. Nice hotel, nice location. . and a Parrot in the Lobby.

It's a block or so from the streetcar. . trolley?. . streetcar I think. (All I know is that the locals rolled their eyes at me when I called it the wrong thing!) Bring exact change - it's $1.25 - and a great ride down a very pretty street, past Tulane. . past the Zoo and I think that great breakfast place is called The Trolley Stop.
Too many great restaurants to mentions. . If you do the 'touristy' ones - Commander's Palace. . Emerils. . you need reservations and men need to wear jackets. Good food at both - but you can eat better for less.
Two of my favorites. . Mr. B's (get the Gumbo Ya Ya!!). .and K Paul's (Paul Prudomme's place). . but, I have also found the best places wandering around and checking out the menus outside.
Bourbon Street is a must. . to say that you have seen it. . but maybe go during the day for Mom & Dad. . on your way to M'ville.

If Mom and Dad are up for it. .there are some great walking tours. . lots of history. .cemetarys. .old houses. . .
Have a great time - it's one of my favorite cities!
