HELP! How do I get noticed at Taylor Swift? Best Answer will be chosen easily.?

I'm going to Gillette Stadium on June 26..soon! It is a big place, I
went to her concert there last year and me and my friend brought
posters. I am going with my mom and my other friend this time. And I
REALLY want to get into the T-Party room (for those who don't know,
Taylor's mom chooses people to go backstage into a fun room and meet
Taylor and the band after the concert, only 25 people get chosen!) I
am 13 and I have wanted to meet Taylor for 3 years. How do I get
noticed? When should I show up? I want to make home-made shirts and
posters but I don't know what me and my friend should write on
them..please help. The best answer will easily be chosen!
Thanks, and please don't comment if you are going to be rude!
