I'm flying my kite at home this year.
What kind of experience are you looking for? If you will already be downtown, there are a ton of resturants / bars / tailgates with TVs and I am sure they will all have the game on with plenty of people around to party with. Saints fans are not really high on the Super Bowl or the NFL for that matter this year, so I am not sure there is a big Saints' fans party being hosted anywhere outside of downtown.
