Taking Kid to First Game

I'm taking my 7 year old to his first ever Wolves game in a couple of weeks. He's super excited!

Does anybody know if they have anything at guest services for first timers, like a certificate or something, like they do at some MLB parks?

Any recommendations? I've been to plenty of games, but I've always just shown up pretty shortly before tip and go right to my seat. Any reason to show up early and show him anything?
