Question about Cosplaying at Madison Square Garden

Quick question about the Cosplaying rules of Madison Square Garden. Since the Summer LCS finals are being held there this year, i'm sure a lot of people will be getting into the spirit. Does anyone know if you'll be allowed to bring weapons, real or fake, inside? Or if they will need to be checked/registered? I'm not sure about it and seeing how it's a very big venue I would think they would (but hope they don't!) have some rules against it. Was just curious if anyone knew if foam, wooden, or even real metal weapons for cosplay would be allowed inside before I make them? thanks :D
