Ok, I need all y'all opinions on a possible parenting dilemma. I swear it's nothing bad this time.

We are actually on a roll with DS and things are good with him. This has to do with DD12.
She will be 13 next month. We just found out that one of her very favorite singers, Taylor Swift, will be going on tour. She is also from our area so we are figuring that she will put a show or two on close to here. I know DD will want to go see her with at least one friend. But I also know she will not want to sit with mom or dad. I've come to grips that we are just "not cool enough anymore".
Anyways, we were thinking that if we have the chance to go, we would get 2 sets of tickets. One set for DD and her friend and one for DH and I a few rows behind them. Our set would only be a couple of rows behind them so that we could see them at all times. Bathroom breaks and such would have to be with one of us. They absolutely would not be allowed to roam the arena on their own.
Does this sound like a good idea? Or is she still too young for this? She's always gone to concerts with us but I know there comes a time when I have to trust her a little more. My dad was way over protective and I don't want to fall into that either.
Ugghhh! I am not looking forward to the teen years with her!!!!!!!!!
