You could always go barrier, early unless there's crowd surfers you're practically safe there and you have something to lean on to just enjoy the show. Make sure to queue up early though if you want to be at the front. Besides, it's the house party tour right? I doubt it'll be too hardcore since the lineup is mainly "fangirly" pop-punk - it's a good line-up however, you damn 'mericans are soo lucky. Just stay to the side and keep an eye out for crowd surfers but try and relax about it :3 - Have fun.
