Last year was my first TFCon and it was a blast...although I probably bought some stuff that I shouldn't have. I would suggest making a list of things you'd like to pick up and it will help establish a budget. I got sidetracked by a few things I saw early on and then missed out on something I really wanted.
Also, it was my first time, so I didn't really participate in some of the events like the karaoke because I was too chicken to talk to people
