Actually one kind of hidden secret is Super Bowl week in the host city. It's actually not that expensive if you come in the weekend before through late of Super Bowl week. Lots of free or cheap concerts and events and studio audience kind of things... Atlanta will be my 13th of the last 18 just for the fun stuff. Only been to one game, would be cool to get to another or get tickets to a more exclusive party kind of thing.
But I'm happy just enjoying winter and a relatively nice winter city that has a lot of cool things beyond just even the Super Bowl stuff. Of course I will admit as a Broncos fan it is super cool when your team makes it. As I'm sure it would be for you if you were there when the Patriots made it. Great synergy
