Honestly it depends. With a raised stage, its much harder to see, now the pit isnt as hardcore as it was either back in the early 2000s either, so moshing will be minor, her being able to see an enjoy the show is another story. Depends where your going to see them, but dead center 1st row to 10th row, is a great place to watch LP, great sound, and you stand up anyways and see a great show, LP is alot about the lasers and light show, visuals now, much more then back in the day. No matter what you will have a good time, but I do think she will have a hard time seeing and enjoying the show from the PIT. You will be picking her up so she can see. I think you will have fun either way you go, but honestly unless you are there to mosh, and leave her standing there, get great dead center close seats. If you and her enjoy moshing and know the songs, hit the pit. But as a first show, and the lights, visual aspect, softer songs of LP now, I think overall you both will enjoy the show from close seats and the sound will be much better in most stadiums as well. I have been to every LP show since 1999 in MD VA OR DC and have brought my daughter, who is now 12, to the pit when she was 7, and she had a great time in the pit a couple times and the energy and love is awesome of the fans in the pit, and most crowds look out for each other. Yours is not a klid, but a small adult, energy, young, pit is great, sound, visuals, enjoying the full show and experience for the first time, I would get close seats, next show get in the pit.
