Don't go that first week, check out all the Pop Warner/Cheerleader threads and you'll see why!
We are going Dec 15-22 this year so the week before Christmas and I have heard it will be a decent week. More crowded as it comes to the end but hoping the first half is good.
I think as long as you avoid the throngs of rude teens you will be fine. I would skip the week between Christmas and NY too, incredibly crowded.
