Is the convention at the Ernest Morial Convention Center (on the Mississippi River, former site of the 1984 World's Fair) or at one of the larger hotels? I ask because I was born and raised in New Orleans.
Let me know where the convention is hosted and I'll be happy to suggest a couple of close hotels.
Bear in mind: if it's at the Morial Convention Center, all the hotels within a 1-2 block walking distance are too far from the touristy parts of the French Quarter. The 300-600 blocks of Bourbon Street, Jackson Square, finer restaurants, etc, are at least a mile from the hotels surrounding the Morial Convention Center. Plus, you do NOT want to be walking through some of the peripheral blocks of the French Quarter by yourself after dark.
So, do you want to stay in the Quarter and take a taxi to the convention, or stay near the convention and taxi everywhere else?
JPP: did you know they reinstalled the Canal Street streetcar, which had been removed in 1964? Plus, now they have another streetcar line, which goes along the riverfront from the Convention Center to Esplanade Blvd? Neither were there when you were at Tulane.
