Jonas Brothers Concert! Hershey Park 7/25/08?

Okay so I am going to this jonas brothers concert and I am so excited! I want to know if there is a meet and greet and if you show up like 6 hours before the show or if you are the first one there do they give you back stage pes or something? Oh and when they are doing their sound check 6 hours before the show are you allowed in the stadium to watch them and if you are do you get to talk to them?
