1st Timer Questions

On a whim I picked up some tickets on stubhub for the June 1st match vs. Dallas in the supporter's section. I will be going w my young kid & my husband. Kid is getting really excited about playing soccer & I think seeing a pro game would reinforce his love of the game. Will it be easy to find a good spot to sit in the higher up area that would be a lil more kid friendly?

Also, is there a good place to buy knock off jerseys? I can't justify spending that much on jerseys for the whole family at this point. I was thinking of going to the fashion district & wandering around, but if I can order online in time that would be awesome. I saw dhgate would take a month or more to receive.

Are there any other tips you have for making this a positive 1st experience for a kid? He's never been to another professional sporting event. We will be spending the night right by the stadium so I don't have to deal w driving late @ night.
