My birhtday is in June (I will be 55 years old) and I want to go to New Orleans to celebrate. This will be the first time I've been to New Orleans a single woman.
The Saint Charles Streetcar is the oldest continuously operating street railway in the world and is a "tourist attraction" in its own right. It is part of the public transit system, as are the Canal Street and Riverfront streetcar lines: www.norta.com
There is always music, but the bands change: Go to www.bestofneworleans.com and click on Music then Listings or to www.offbeat.com and click on Listings, then Music.
Note that music clubs often advertise "No Cover", meaning there is no charge for entering. However, clubs with "No Cover" often require that customers buy a beverage each for every "set" of music (which can be every 20 minutes) so KNOW THE PRICE before you sit down. Clubs do that because some people will sit in the club all evening drinking nothing (clubs only make money from the drinks they sell - not from the music). It is also a good idea to pay for each round of drinks (in clubs on Bourbon Street) as it is delivered so there can't be any confusion at the end of the evening.
About certain alcoholic beverages: Realize that some famous drinks are VERY potent compared with regular cocktails that have only 1 to 1 ½ ounces of alcohol. For example, a Hurricane is basically 3 or 4 ounces of rum in something like red Kool-Aid, and a Hand Grenade has at least 4 ½ ounces of Everclear + rum + vodka mixed with melon liquor. They don’t necessarily taste like an alcoholic beverage and it is easy to over-indulge.
Wander around the French Quarter, enjoy the architecture, watch the street entertainers (do tip), and visit some of the historic buildings that have been turned into museums (go to www.frenchquarter.com and click on Historic Attractions).
Cafe du Monde is in the French Quarter and you shouldn't miss having cafe au lait & beignets (www.cafedumonde.com). Another great coffee shop is the Croissant d'Or (at 617 Ursulines Street), which is open from 7:00am to 2:00pm and has food in addition to pastry.

There is a free ferry across the Mississippi at the "foot" of Canal Street. It is a short trip but like a harbor cruise w/o a guide: http://en.wikipedia.org/wiki/canal_street_ferry
The Aquarium, Audubon Zoo, and the new Insectarium are world-class attractions (www.auduboninstitute.org) and you should see them if you can. The Zoo is several miles from downtown. You can drive to the Zoo (which has free parking) or take public transit from the French Quarter.
