I'm a bit disappointed with this as well, used to the amusement park, etc. type of closing event. My guess is the superdome was so expensive to rent that it left little $$ to do anything else with. This is the first time my wife is coming with me, I've been touting the closing party for months and when we found out it was this, it was really disappointing.
I guess if there's free alcohol we can get our monies worth in top shelf liquor :/ Can't believe I paid an extra $125 for her to go, money not well spent.
Here's to hoping there's some unannounced surprise!
