Your first time to a Con will be a memorable event. That you chose Dragon Con can make it even more so. Dragon Con is less of a gaming Con and more of a Movie and TV Con. Gaming can be found but that isn't the focus of the Con like it is at, say, Gen Con. Dragon Con is a party Con and the party truly never ends. Be sure to see the costume parade on, I think, Saturday night. Your days will likely be spent just walking around and seeing stuff, and maybe taking game demos.
