re: Visitor Info

I would think the street car would be running pretty late that night, but it may be tough to find a spot. Getting down there via streetcar will be easy that day.
As far as getting back, I'd walk toward the River from the dome and look for a cab back to the garden district. Lot's of places in the Warehouse Dist. (to the right as you walk down poydras toward the river)to get a drink or something to eat if the cabs are hard to get. Warehouse Dist, around the Dome, and the route back to your hotel is safe....don't listen to these idiots.
