Well, I must admit being disappointed too. The Mardis Gras Museum was great, but mostly because of the music.
The party at the Aquarium was great too, because of the food and the music and the outdoor venue.
I've been to a Superdome party before and they can be great. Top notch music acts are very likely. Food should be good too. The fairground rides and stalls I can do without, personally. There really had better be decent beer though.
